Skin contact and remote hugs via smart textiles

Smart textiles are making virtual reality more immersive and enabling wearers to experience the sensation of physical touch. An ultrathin film that can transmit touch sensations is able to turn textiles into a virtual second skin. For seriously ill children in hospital isolation wards, this new technology offers them the chance to feel the physical closeness of their parents during computer-simulated visits and to experience again the feeling of being held, hugged or cuddled.

The research team led by Professors Stefan Seelecke and Paul Motzki from Saarland University will be presenting the technology behind these smart textiles at Hannover Messe from 22 to 26 April.

A hand on a shoulder, the stroke of an arm or a simple hug. Human touch can bring calm, comfort and closeness, a sense of safety and of being protected. When the nerve cells in our skin are stimulated by touch, numerous parts of our brain are triggered, causing immediate changes in our body's biochemistry. Hormones and signalling molecules are released, including oxytocin, which creates a sense of well-being and bonding. Video calls, on the other hand, tend to leave us cold. We miss the closeness and emotional connection that in-person meetings produce. But what happens when physical closeness is essential, when children are seriously ill, but their parents are unable to visit? When physical contact is not possible due to a weakened immune system?

An interdisciplinary research team at Saarland University, htw saar University of Applied Sciences, the Centre for Mechatronics and Automation Technology (ZeMA) and the German Research Center for Artificial Intelligence (DFKI) is working on a technology that will enable children in hospital isolation wards to feel in a very natural way the close physical proximity of their parents during virtual visits. The 'Multi-Immerse' project is at the interface of engineering science, neurotechnology, medicine and computer science and the members of the research team are developing ways to realize multi-sensory virtual encounters between individuals. The aim is to create new technology that will allow young patients to see, hear and feel their parents and siblings in as realistic a manner as possible so that the children experience a strong sense of close physical interaction even though they are physically separated.

The research group led by Professors Stefan Seelecke and Paul Motzki at Saarland University and ZeMA in Saarbrücken is responsible for the tactile side of the project and for creating technical systems that deliver a realistic sense of touch. The Saarbrücken engineers are experts in using thin silicone films to impart novel capabilities to surfaces. They have developed films that are a mere 50 micrometres thick and that can be worn like a second skin. Just as our skin is our body's interface to the outside world, these ultrathin films are the body's interface to the virtual world. The goal is to create a lifelike sensation of touch from interactions between people in a virtual environment.

When incorporated into textiles, these high-tech films allow the child to experience being touched when the mother or father strokes a second smart textile elsewhere. 'The films, known as dielectric elastomers, act both as sensors – detecting the tactile input from mum or dad – and as actuators – that transmit these movements to the child,' explained Professor Seelecke, who heads the Intelligent Material Systems Lab at Saarland University. When functioning as a sensor, the film is able to recognize with very high precision how a hand or finger presses or stretches the film as it brushes over it. This physical deformation caused by the parent's hand is then reproduced exactly in a second textile that is in contact with the child's skin – giving the child the realistic impression of being stroked on the arm, for example.

‘A highly flexible electrically conducting layer is printed onto each side of the ultrathin film to create what is known as a dielectric elastomer. If we apply a voltage to the elastomer film, the electrodes attract each other, compressing the polymer and causing it to expand out sideways, thus increasing its surface area,' said Professor Paul Motzki, who holds a cross-institutional professorship in smart material systems for innovative production at Saarland University and at ZeMA. Even the slightest movement of the film alters its electrical capacitance, which is a physical quantity that can be precisely measured. When a finger runs over the film, the film deforms and an exact value of the electrical capacitance can be assigned to each individual position of the film. A sequence of these measured capacitance values represents the path taken by the finger as it moves. The film is therefore its own flexible sensor that can recognize how it is being deformed.

By knowing how capacitance values and film deformations correlate, the researchers can use the smart textile to transfer the stroking motion of a parent's hand to the child's arm. The research team is able to precisely control the motion of the elastomer film. By combining the capacitance data and intelligent algorithms, the team has developed a control unit that can predict and program motion sequences and thus precisely control how the elastomer film deforms. 'We can get the film to perform continuously controlled flexing motions so that it exerts increasing pressure on the skin, or we can get it to remain in a fixed position”, explained PhD student Sipontina Croce, who is carrying out doctoral research in the project. They can also create tapping movements at a specified frequency. The amplitude and frequency of the motion can be precisely regulated.

At this year's Hannover Messe, the team will be demonstrating their technology with a “watch” that has a smart film applied to its back. 'We can create chains of these smart components so that they can transmit long stroking motions. To do this, we interconnect the components so that they can communicate and cooperate collectively within a network,' explained Paul Motzki.

This smart-textile technology is inexpensive, lightweight, noiseless and energy-efficient. By providing a tactile element to computer gaming, the novel elastomer-film technology can also be used to make the gaming experience more realistic. In related projects, the engineers have used their technology to create interactive gloves for future industrial production processes, or to create the sensation of a tactile 'button' or 'slider' on flat glass display screens, which is literally bringing a new dimension to touchscreen interactions.

At this year's Hannover Messe, the experts for intelligent materials from Saarbrücken will be showcasing other developments that make use of dielectric elastomers, such as sensory shirts or shoe soles, or industrial components like pumps, vacuum pumps and high-performance actuators.

Smart glove teaches new physical skills

Adaptive smart glove from MIT CSAIL researchers can send tactile feedback to teach users new skills, guide robots with more precise manipulation, and help train surgeons and pilots.

You’ve likely met someone who identifies as a visual or auditory learner, but others absorb knowledge through a different modality: touch. Being able to understand tactile interactions is especially important for tasks such as learning delicate surgeries and playing musical instruments, but unlike video and audio, touch is difficult to record and transfer.

Adaptive smart glove from MIT CSAIL researchers can send tactile feedback to teach users new skills, guide robots with more precise manipulation, and help train surgeons and pilots.

To tap into this challenge, researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and elsewhere developed an embroidered smart glove that can capture, reproduce, and relay touch-based instructions. To complement the wearable device, the team also developed a simple machine-learning agent that adapts to how different users react to tactile feedback, optimizing their experience. The new system could potentially help teach people physical skills, improve responsive robot teleoperation, and assist with training in virtual reality.

Will I be able to play the piano?
To create their smart glove, the researchers used a digital embroidery machine to seamlessly embed tactile sensors and haptic actuators (a device that provides touch-based feedback) into textiles. This technology is present in smartphones, where haptic responses are triggered by tapping on the touch screen. For example, if you press down on an iPhone app, you’ll feel a slight vibration coming from that specific part of your screen. In the same way, the new adaptive wearable sends feedback to different parts of your hand to indicate optimal motions to execute different skills.

The smart glove could teach users how to play the piano, for instance. In a demonstration, an expert was tasked with recording a simple tune over a section of keys, using the smart glove to capture the sequence by which they pressed their fingers to the keyboard. Then, a machine-learning agent converted that sequence into haptic feedback, which was then fed into the students’ gloves to follow as instructions. With their hands hovering over that same section, actuators vibrated on the fingers corresponding to the keys below. The pipeline optimizes these directions for each user, accounting for the subjective nature of touch interactions.

“Humans engage in a wide variety of tasks by constantly interacting with the world around them,” says Yiyue Luo MS ’20, lead author of the paper, PhD student in MIT’s Department of Electrical Engineering and Computer Science (EECS), and CSAIL affiliate. “We don’t usually share these physical interactions with others. Instead, we often learn by observing their movements, like with piano-playing and dance routines.

“The main challenge in relaying tactile interactions is that everyone perceives haptic feedback differently,” adds Luo. “This roadblock inspired us to develop a machine-learning agent that learns to generate adaptive haptics for individuals’ gloves, introducing them to a more hands-on approach to learning optimal motion.”

The wearable system is customized to fit the specifications of a user’s hand via a digital fabrication method. A computer produces a cutout based on individuals’ hand measurements, then an embroidery machine stitches the sensors and haptics in. Within 10 minutes, the soft, fabric-based wearable is ready to wear. Initially trained on 12 users’ haptic responses, its adaptive machine-learning model only needs 15 seconds of new user data to personalize feedback.

In two other experiments, tactile directions with time-sensitive feedback were transferred to users sporting the gloves while playing laptop games. In a rhythm game, the players learned to follow a narrow, winding path to bump into a goal area, and in a racing game, drivers collected coins and maintained the balance of their vehicle on their way to the finish line. Luo’s team found that participants earned the highest game scores through optimized haptics, as opposed to without haptics and with unoptimized haptics.

“This work is the first step to building personalized AI agents that continuously capture data about the user and the environment,” says senior author Wojciech Matusik, MIT professor of electrical engineering and computer science and head of the Computational Design and Fabrication Group within CSAIL. “These agents then assist them in performing complex tasks, learning new skills, and promoting better behaviors.”

Bringing a lifelike experience to electronic settings
In robotic teleoperation, the researchers found that their gloves could transfer force sensations to robotic arms, helping them complete more delicate grasping tasks. “It’s kind of like trying to teach a robot to behave like a human,” says Luo. In one instance, the MIT team used human teleoperators to teach a robot how to secure different types of bread without deforming them. By teaching optimal grasping, humans could precisely control the robotic systems in environments like manufacturing, where these machines could collaborate more safely and effectively with their operators.

“The technology powering the embroidered smart glove is an important innovation for robots,” says Daniela Rus, the Andrew (1956) and Erna Viterbi Professor of Electrical Engineering and Computer Science at MIT, CSAIL director, and author on the paper. “With its ability to capture tactile interactions at high resolution, akin to human skin, this sensor enables robots to perceive the world through touch. The seamless integration of tactile sensors into textiles bridges the divide between physical actions and digital feedback, offering vast potential in responsive robot teleoperation and immersive virtual reality training.”

Likewise, the interface could create more immersive experiences in virtual reality. Wearing smart gloves would add tactile sensations to digital environments in video games, where gamers could feel around their surroundings to avoid obstacles. Additionally, the interface would provide a more personalized and touch-based experience in virtual training courses used by surgeons, firefighters, and pilots, where precision is paramount.

While these wearables could provide a more hands-on experience for users, Luo and her group believe they could extend their wearable technology beyond fingers. With stronger haptic feedback, the interfaces could guide feet, hips, and other body parts less sensitive than hands.

Luo also noted that with a more complex artificial intelligence agent, her team's technology could assist with more involved tasks, like manipulating clay or driving an airplane. Currently, the interface can only assist with simple motions like pressing a key or gripping an object. In the future, the MIT system could incorporate more user data and fabricate more conformal and tight wearables to better account for how hand movements impact haptic perceptions.

Luo, Matusik, and Rus authored the paper with EECS Microsystems Technology Laboratories Director and Professor Tomás Palacios; CSAIL members Chao Liu, Young Joong Lee, Joseph DelPreto, Michael Foshey, and professor and principal investigator Antonio Torralba; Kiu Wu of LightSpeed Studios; and Yunzhu Li of the University of Illinois at Urbana-Champaign.

The work was supported, in part, by an MIT Schwarzman College of Computing Fellowship via Google and a GIST-MIT Research Collaboration grant, with additional help from Wistron, Toyota Research Institute, and Ericsson.

Silk Provides the Building Blocks to Transform Modern Medicine

Tufts researchers harness protein from silk to make virus-sensing gloves, surgical screws that dissolve in your body, and other next-generation biomedical materials

About a mile northwest of Tufts’ Medford/Somerville campus, on the fourth floor of a refurbished woolen factory, there is a shrine to silk. Glass vases filled with silkworm cocoons and washed silk fibers sit artfully on a shelf across from a colorful drawing of the life cycle of Bombyx mori, the domesticated silk moth. Farther in, more cocoons in wall-mounted cases border a large, close-up image of silk fibers, and displays hold dozens of prototypes made from silk, including smart fabrics, biosensors, a helmet that changes color upon impact, and potential replacements for materials like leather, plastic, and particle board.

Tufts researchers harness protein from silk to make virus-sensing gloves, surgical screws that dissolve in your body, and other next-generation biomedical materials

The only things missing are the silkworms themselves, but Fiorenzo Omenetto, the director of Silklab and the Frank C. Doble Professor of Engineering at Tufts, said they will be arriving soon. The lab is building a terrarium so that visitors can view the animals.
“We’re going to have a celebration of silkworms and moths,” Omenetto said.

Silk has been cultivated and harvested for thousands of years. It is best known for the strong, shimmering fabric that can be woven from its fibers, but it also has a long history of use in medicine to dress injuries and suture wounds. At Silklab, Omenetto and his colleagues are building on silk’s legacy, proving that this ancient fiber could help create the next generation of biomedical materials.

Silk moth caterpillars, known as silkworms, extrude a single sticky strand of silk from their mouths to form cocoons, which are harvested by silk farmers to make silk thread. At its core, silk is a mixture of two proteins: fibroin, which provides the fiber’s structure, and sericin, which binds it together. With a few steps in the lab, Tufts researchers can remove the sericin and dissolve the fibers, turning a dry cocoon into a fibroin-filled liquid.

“Nature builds structural proteins that are very tough and very strong,” Omenetto said. “Your bricks are these fibroin proteins floating in water. From there, you can build whatever you want.”
Starting with shipments of dried cocoons from silk farms, Omenetto and his colleagues have been able to create gels, sponges, clear plastic-like sheets, printable inks, solids that look like amber, dippable coatings, and much more.

“Each of the materials that you make can contain all these different functions, and there’s only 24 hours in a day,” Omenetto said with a laugh. “This is why I don’t sleep.”

Biocompatible and Biodegradable
When Omenetto arrived at Tufts almost two decades ago, his research was focused on lasers and optics—silk wasn’t in the picture. But a chance conversation with David Kaplan, the Stern Family Professor of Engineering and chair of the biomedical engineering department, set him on a new path.

Kaplan, who has been working with silk since the early ’90s, was designing a silk scaffold that would help rebuild a person’s cornea, allowing cells to grow between the layers. He needed a way to ensure that the growing cells would have enough oxygen and showed the small, transparent sheet to Omenetto, who was immediately intrigued by the material. Omenetto was able to use his lab’s lasers to put tiny holes in Kaplan’s silk cornea. More collaborations quickly followed.
“We’ve worked together incessantly since then,” Kaplan said.

One of those lines of research has been finding ways to use silk to help repair and regrow bone, blood vessels, nerves, and other tissue. Silk is biocompatible, meaning it doesn’t cause harm in the body and breaks down in predictable ways. With the right preparation, silk materials can provide necessary strength and structure while the body is healing.

“You can mold and shape silk to whatever you need, and it will hold that volume while the native tissue regrows into the space and the silk material degrades,” Kaplan said. “Eventually it’s 100 percent gone, and you’re back to your normal tissue.”

Some of this work has already been approved for use by the U.S. Food and Drug Administration. A company called Sofregen, which spun out of Kaplan and Omenetto’s research, is using an injectable silk-based gel to repair damaged vocal cords, the tissues that regulate air flow and help us speak.

On their own, sturdy silk structures can keep their size, shape, and function for years before degrading. But in some instances, such as those involving surgical screws and plates intended for use in rapidly growing children, this pace would be too slow. The researchers had to find a way to speed up the time it takes for dense silk biomaterials to break down. They introduced an enzyme that our bodies produce naturally into the silk to hasten the breakdown process. The idea is that the enzyme would sit dry and inactive within the silk device until the structure is installed in a person, then the device would hydrate and activate the enzyme to digest the material more rapidly.

“We can titer in just the right amount of enzyme to make a screw go away in a week, a month, a year,” Kaplan said. “We have control over the process.”

Currently, Kaplan and his lab are working on other small, degradable medical devices that would help cut down on the number of surgeries that patients need. Ear tubes, for example, are often surgically implanted to help alleviate chronic ear infections and then need to be surgically removed. Kaplan and his colleagues have designed silk-based ear tubes that degrade on their own and can even carry antibiotics.

“As someone with a daughter who went through six surgeries on her ear, I know how helpful this could be,” Kaplan said.

Nopma - Experts for antimicrobial finishing: Technical textile coatings from the Swabian Alb

The Carl Meiser GmbH & Co. KG - started in the early 1950s as a day- and nightwear manufacturer. Over the last 20 years the company has become a specialist in the field of technical textiles. With its brand nopma Technical Textiles the company is present as developer and producer of textile solutions via coatings. The main products are nopma anti-slip - textiles with anti-slip effect, nopma adhesion - adhesive pre-coated films, spacer fabrics and substrates for lamination in automotive interiors, nopma ceramics - abrasive more resistant textile surfaces and nopma silicones - silicone coatings on textile surfaces.

Textination talked to the managing director, Jens Meiser, who joined the company in 2005, realigned the division and developed it into a service provider, about his plans and objectives.

Founded in 1952, Carl Meiser GmbH & Co.KG has changed from a day- and nightwear manufacturer to an innovator in the field of technical textiles, presenting themselves as a specialist for plastic-based coating processes. If you had to introduce yourself in 100 words to someone who does not know the company: What has influenced you most in this development process and what makes you unique?
Innovation is the new normal - This has been true for the textile industry not just since Sars CoV-2. Our industry was one of the first to be disrupted in the early 1990s and has always been subject to constant change. This urge for further development, which is essential for survival, has left its mark on us intensively and has enabled us to manage huge leaps in innovation in recent years

Today we regard ourselves as an innovative development and production service provider with a focus on textile coating. We develop and produce almost exclusively customized special solutions.

Through the combination of coatings on textiles these hybrid materials receive completely new properties.

You manufacture exclusively at your location in Germany. Why? Have you never been tempted to set up subsidiaries in other countries, for example to benefit from lower wage levels?
Today we supply global supply chains from our headquarter in southern Germany. Although we produce in a high-wage country, much more important for us are know-how and the drive of our team to create something new. Globalization will continue to be the key to success in the future. Therefore, subsidiaries in North America and Asia could be very interesting for us in the medium- and long-term perspective. However, this is still too early for us.

You use CIP and Kaizen techniques intensively in your company. How did a Japanese concept come about in the Swabian Alb?
KAIZEN, the change for the better, are actually German virtues. The urge to improve and optimize things is in all of us. Due to the continuous improvement process we do not stand still but evolve constantly. Besides, there is the personal affinity to Japan. A look at another culture simply opens the horizon. And if you additionally recognize parallels in the working methods, it’s even better.

10 years ago, you turned your attention to new markets: aviation, automotive, protection, caravan and furniture manufacturing, to name just a few. Some of these segments have collapsed significantly during the Covid 19 pandemic. What market development do you expect in the medium term and what consequences will this have for your company?
Of course, the aviation or automotive industry, for example, have substantial problems during or due to the Covid-19 pandemic. Quite honestly, many of these problems existed before. They were further tightened, as if a fire accelerator has been used. Of course, these cut-backs are also hitting us hard economically. But we are pursuing long-term goals. As a medium-sized company, you have to have the resilience to continue on your path. Thanks to our specialisation and the split of our industrial sectors, which we drive forward every day, we manage to decouple ourselves more and more from economic developments in individual industries. For our customers this is a great advantage of relying on a very stable partner with long-term orientation.

We are positive about the future. Megatrends like sustainability, digitization and ongoing globalization will lead to new business models in the above-mentioned sectors, as in many others, and to renewed growth. Our coatings on textiles and flexible woven materials can contribute a wide range of solutions to this. If, for example, materials become lighter with identical usage properties or suddenly become biodegradable, because of biodegradable plastics, many new opportunities will arise.

Tailor-made instead of solutions for major customers: The topic of individualization down to batch size 1 is making up a large part of the discussion today. In 2015, you opened a large development laboratory where you have a wide range of testing technologies for textiles and plastics available. What do you think about individual product solutions, and in which application areas have you successfully implemented them?
In principle, we do not use any standards. We live individualization with the smallest possible batch sizes. In our field, we do not manage batch size 1, but we start with MOQs of 300 running meters at process-safe series production. We have very few finished products, and above all we have no collections. Our development laboratory is the key for this. Together with our customers we have the possibilities to realize very lean development processes.

Even on a laboratory scale, we can develop and test new products within just a few hours. We then strive to scale up to production at a very early stage in order to obtain production series results. This way, we offer our clients speed and power that represent a special potential for our partners.

You register important input factors in the production process and evaluate them in monthly environmental analyses. What are these factors in concrete terms and to what extent have their analyses already changed production operations? How do you define environmental management for your company?
For us, environmental management means a holistic approach. In principle, we operate production units and manufacture products that consume many resources. Due to the high production volumes, this continues to accumulate. Because of this, it is self-understanding that we record and evaluate our input and output flows and derive measures from them. This makes economic sense, but is also necessary because of our responsibility for our environment. Specifically, these are energy consumption values, consumption data of primary chemicals, electricity load peaks, our Co2 footprint, just to name a few. This consideration has changed us in many areas. Today we operate a power plant with gas condensing technology, our free roof areas are greened or carry photovoltaic modules, we offer our employees and visitors electric filling stations and finally we have converted the entire power supply of our factory to environmentally friendly hydroelectric power.

With nopma, you have been building up a brand for the technical textiles industry since several years and communicate this via an Individual website parallel to Carl Meiser GmbH & Co. KG. How did this brand name come about and what is the product portfolio behind it?
This is the name of a first technical textile product from the 1990s. It was a textile - coated with dots. Dots on a knitted fabric. NOPMA. My father created this brand.

In 2016 you invested in an additional production line for nopma products and were able to start a directly serial delivery in the NAFTA area. How do you currently assess the market opportunities for North America and Mexico?
We continue to see opportunities in globalization and thus on the North American market also. However, these markets are still severely affected by the pandemic and there are major distortions. When these return to normal, we surely will see more success on these markets again.

As an innovation leader, Meiser offers solvent-free PU adhesive systems as pre-coatings for lamination. How do you assess the importance of such innovations in the context of REACH?
These innovations offer our customers the opportunity to decouple themselves from the pressure REACH triggers in some industries. However, we also have some products that have been developed newly in recent months. This keeps us busy, but also creates opportunities to open up new market segments.

How have you felt about the corona era to date - as a company and personally? What would you on no account want to go through again and what might you even consider maintaining on a daily basis?
I think this time has also strengthened us as a society, as people and even as entrepreneurs. Each crisis you go through makes you a little more relaxed for the unforeseen, but also more motivated to achieve your goals. In my opinion, there have been a lot of positive things in the last few months. Suddenly, for example, digitalization tools have become accepted in our everyday lives, and I feel that people are paying more attention to others again. Hopefully this will stay this way.

The futuristic "tube" escalator at the Elbphilharmonie Concert Hall is just as impressive as the building itself and the longest escalator in western Europe. In August, a start-up based in Cologne installed an UV technology that keeps the handrails clean at all times. At the same time, you presented an antiviral functional coating that can be applied to all textiles in the form of yard goods. How does this work and for what purposes will this technology be suitable?
We have already been working with antimicrobial finishing techniques for many years. This already started with the swine flu in 2009/2010, when we made initial contacts with a young start-up and launched a development. Due to a lack of market interest, however, this had to be discontinued after a few months. Today we are experts in the field of "antimicrobial equipment by means of coatings". We were also able to build up an enormous amount of knowledge on the subject of approval and biocide regulation. Today, we can support our customers holistically in these areas. The function by skin-compatible active substances from the cosmetics sector with a vesicle booster can kill viruses and bacteria within a few minutes.
Since the pandemic has shown us the enormous importance of a new level of hygiene, the applications are very diverse and differentiated. We have already realized the use in personal protective equipment, work furniture, vehicles and for example gloves. In principle, every application is predestined where textile carriers are exposed to many touches by different persons in high frequency. Here our nopma products offer a new level of protection and hygiene.

To break new ground means decisiveness, overcoming fears - and thus the courage to fail. Not every project can succeed. In retrospect - about which entrepreneurial decision are you particularly glad to have made it?
We fail again and again. This is part of the game. But it has never happened that we did not learn anything. The pandemic situation is another good example. In spring we accepted our corporate responsibility for our society and were one of two companies in Baden-Württemberg to achieve certification for FFP protective masks. Since we did not want to participate in the revolver market at that time, we offered these products only to the public sector at favourable pre-crisis prices. However, the decision makers could not make up their minds for weeks and did not order. This disappointed our whole team very much at that time. Today we have overcome this and have taken a lot of knowledge with us from this development.

TÜV Rheinland tests Corona Protection Materials and Occupational Safety Projects

Since the outbreak of the global corona pandemic, the production and trade of suitable protective materials such as respiratory masks have become a high-risk area for all those involved.

"The quality and safety of the protective materials on offer is currently not only subject to considerable fluctuations, but more and more frequently goods are coming from dubious sources, are highly questionable in terms of hygiene, and in some cases completely unusable", explains Dipl.-Ing. Ralf Scheller, member of the Board of Management of TÜV Rheinland AG. "We are in direct contact with governments, ministries, local authorities and companies in the health sector worldwide and are increasingly experiencing cases and incidents in which supply chains simply collapse and overpriced goods do not arrive.

Since the outbreak of the global corona pandemic, the production and trade of suitable protective materials such as respiratory masks have become a high-risk area for all those involved.

In some cases, criminal activity is behind this, for example when certificates are forged or goods are sold several times. This is why the experts in personal protective equipment (PPE) at TÜV Rheinland are increasingly being called in for on-site assignments in the manufacturing countries. They test the protective materials in their worldwide network of laboratories directly on site, check documents or monitor the transportation of goods from the manufacturer to the customer.

Support and assistance for multinational aid projects
"Since the beginning of the pandemic, we have been supporting many multinational aid projects and are involved ourselves even in the Heinsberg district, where we have donated 9,000 FFP3 protective masks for the intensive medical care sector," explains Scheller. "Our colleagues in China have also recently supported a relief shipment of several million protective masks, protective clothing and gloves as well as many respirators through quality assurance measures in the supply chain, which was sent to the UK by a private donor".

When it comes to personal protective equipment, TÜV Rheinland's focus is on safety and quality. This makes it all the more important that safety clothing meets the relevant requirements so that its protective function can be guaranteed.

"Our experts carry out all relevant tests and certifications on personal protective equipment in accordance with PPE Regulation 2016/425. Thanks to many years of active committee work in the field of PPE, we are close to the market and have extensive know-how," knows Dr.-Ing. Kristina Fuhrmann, Head of the Textiles and PPE Department at TÜV Rheinland. "The specialist expertise we have gained in this way flows into our daily work and is reflected in our comprehensive services". For example, so-called "community masks" are subjected to numerous chemical and physical tests according to our own test specifications (2PFG S 0193/04.20) and can also be provided with a TÜV Rheinland test mark (tested for harmful substances). Community masks are mainly made of textile materials and serve as a barrier. Medical masks and surgical masks, on the other hand, can be tested or inspected by TÜV Rheinland Greater China. "Our services cover many types of protective clothing", says Fuhrmann. Added to this is the large range of medical products, such as respiratory equipment.

TÜV Rheinland also supports occupational safety projects in corona times
Shops, furniture stores and electronic markets are allowed to reopen, businesses are starting up their production as usual - the following applies to all of them: infection protection for employees must meet increased requirements and normal occupational health and safety must continue to be met. The framework for the extended protective measures is provided by the SARS-CoV-2- occupational safety standard of the Federal Ministry of Labor. Employers are obliged to define and implement suitable measures for their company and to monitor the control. The solutions are as individual as the companies themselves: Whereas in a production plant it is necessary to straighten out shift schedules and minimize employee contact, a sales outlet faces different challenges: For example, how can customer flows be managed to maintain minimum distances? How will customer advisors, cashiers or suppliers be protected?

"Our experts have developed a detailed guideline for the SARS-CoV-2 occupational safety standard of the Federal Ministry of Labor and Social Affairs to advise and support companies in the complex implementation of the strict requirements", explains Dipl.-Ing. Norbert Wieneke, business unit manager for company health management, occupational medicine and occupational safety at TÜV Rheinland. The requirements of the SARS-CoV-2 occupational health and safety standard include personal, organizational and constructional hygiene measures as well as the corresponding instructions. They go hand in hand with, and far beyond, offers of occupational medical and psychological advice for employees and risk groups. It is the employer's responsibility to identify suspected cases of corona among employees and, if an infection is detected, to establish a routine for pandemic preparedness in the company. In order to do justice to this comprehensive task, the expertise of occupational physicians, occupational safety specialists, industrial psychologists and health experts is required. These experts already work successfully together in TÜV Rheinland's interdisciplinary teams and implement cross-sector projects for their customers.

UZBEKISTAN PUSHES FOR GLOBAL SHOE AND LEATHER MARKET

Projects worth USD 52 million planned

Tashkent (GTAI) - Uzbekistan wants to become an international player in the shoe and leather industry. The market offers foreign companies a lot of potential for cooperation.

The Government of Uzbekistan has adopted a new initiative for the modernization and expansion of the leather, footwear, leather goods and fur industries. It is aimed at increasing efficiency and expanding production as well as accelerating integration into the international market. Producers are focusing primarily on Russia and Kazakhstan, but also on Western markets such as France. Foreign companies are welcome to participate in the planned projects. In the long term, value chains are to be created, clusters established and exports promoted.

Projects worth USD 52 million planned

Tashkent (GTAI) - Uzbekistan wants to become an international player in the shoe and leather industry. The market offers foreign companies a lot of potential for cooperation.

Cooperation with Uzbek companies are possible in the production of leather goods, passive contract finishing, supply of equipment, auxiliary materials and chemicals to companies or in the trade with footwear, leather and fur goods. There are plenty of high-quality raw materials and a large potential of available and motivated workers.

The framework conditions for companies in Uzbekistan have improved noticeably. Labor and energy costs are low. In 2017, the government initiated economic liberalization and opening of the country. Uzbekistan wants to more than double its shoe exports by 2020. In 2017 Uzbek manufacturers sold shoes worth USD 150 million abroad.

Foreign investors are planning new projects
The O´zcharmsanoat's key 2019 investment program lists projects valued at USD 52 million. In addition, there are other projects which have not yet been included in the program due to ongoing coordination with potential foreign investors or which are planned in companies that operate outside O´zcharmsanoat.
An overview of current and planned projects for the development of the leather, shoe, leather goods and fur industry in Uzbekistan can be downloaded here.

Association O´zcharmsanoat is the main contact partner
The Association of the Leather Industry O´zcharmsanoat acts on behalf of the state as the central regulator and coordinator of the sector. It was restructured in May 2018 and controls, among other things, investments and foreign trade. Almost all notable Uzbek players in the leather industry are active under its umbrella. These include 30 automated slaughterhouses (supplied by livestock farms), 63 tanneries, including pre-tanning facilities, 131 shoe manufacturers and 28 producers of other products, including fur products (as of June 30th 2018). It also operates 13 warehouses for the purchase of raw materials from private animal breeders.

The leather processing companies produce hard leather (foot and insole leather) and upper leather, mainly chrome leather goods and Russia leather. The annual raw material supply amounts to around nine million hides and five million skins. About two fifths of this volume is currently exported. Among the 252 companies, which are employing about 26,000 people, there are 47 companies with foreign capital participation as well as numerous purely private Uzbek companies.

Only about a dozen of the 131 shoe manufacturers, which are currently active at O´zcharmsanoat, employ 100 people or more. The development of efficient medium-sized structures in the sector is still in its infancy and is likely to gain momentum.

Government grants tax and tariff preferences for five years
The slaughterhouses and manufacturers of raw, semi-finished and finished goods as well as the new foreign trade company Uzcharmimpex will receive tax and customs relief. These apply to existing companies of the association O´zcharmsanoat until January 1st 2023. Newly established companies can benefit from the preferences for five years from the date of company foundation.
In detail, the following preferential conditions are granted:

Exemption from the profit and wealth tax or the uniform tax levy for micro and small companies
Exemption from compulsory contributions to earmarked central funds
Exemption from import duties for the import of equipment, completion parts, raw materials and materials which cannot be procured in the country and are intended for production.
Granting a 60-day deferment of payment of import duties (from the date of the customs declaration) for the import of all other equipment, completion parts, raw materials and supplies and other goods for production needs
VAT exemption for imports of raw materials and intermediate products for the use in production and of equipment for footwear production

Uzcharmimpex imports equipment for Uzbek companies
The foreign trade company Uzcharmimpex is engaged both in the export of sector products and in the import of equipment, spare parts, auxiliary materials and chemicals. The list of imported capital goods includes butchery, cutting, slicer, splitting and shaping machines, vacuum dryers, electronic measuring instruments for leather surface measurement, sewing machines and footwear assembly equipment.

The industry modernization initiative also provides for the creation of an industry development fund. This is fed by a levy amounting to 5 percent of export earnings from chrome-tanned hides and skins that have not yet been dressed (wet blue). These funds are intended for investment projects, the granting of loan guarantees, the financing of ISO certifications, the promotion of trade fair participations and the promotion of training and further education.

Usbekistan doubles shoe production
According to the Association of the Leather Industry O´zcharmsanoat, about 40 million pairs of shoes were produced in Uzbekistan in 2017, including 17 million pairs of full and partial leather shoes. An output of 34.2 million pairs of leather shoes is planned for 2020. Then the leather production is expected to reach a volume of 1.3 billion square decimeters. For 2018, the association expects 1 billion square decimeters of leather. O´zcharmsanoat aims to increase its total exports to USD 480 million by 2020 and to USD 1 billion by 2025 (Actual 2017: USD 150 million).

The collapse of the Soviet Union, a failed privatization policy and a difficult business climate led to a breakdown in production in the mid-1990s to around 2009/2010. On average, manufacturers produced less than four million pairs of shoes a year. Previously, around 30 medium-sized manufacturers brought 50 million pairs of shoes onto the market each year. In addition, 2.4 million bags and 200,000 pairs of gloves were produced annually. After 2010, there was a start-up boom in the sector thanks to preferential tax arrangements for particularly small companies.
