Intelligent Patch for Remote Monitoring of Pregnancy

During pregnancy, regular medical check-ups provide information about the health and development of the pregnant person and the child. However, these examinations only provide snapshots of their state, which can be dangerous, especially in high-risk cases. To enable convenient and continuous monitoring during this sensitive phase, an international research consortium is planning to further develop the technology of smart textiles. A patch equipped with highly sensitive electronics is meant to collect and evaluate vital data. In addition, the sensors will be integrated into baby clothing in order to improve the future of medical monitoring for newborns with the highest level of data security.

During pregnancy, regular medical check-ups provide information about the health and development of the pregnant person and the child. However, these examinations only provide snapshots of their state, which can be dangerous, especially in high-risk cases. To enable convenient and continuous monitoring during this sensitive phase, an international research consortium is planning to further develop the technology of smart textiles. A patch equipped with highly sensitive electronics is meant to collect and evaluate vital data. In addition, the sensors will be integrated into baby clothing in order to improve the future of medical monitoring for newborns with the highest level of data security.

The beginning of a pregnancy is accompanied by a period of intensive health monitoring of the baby and the pregnant person. Conventional prenatal examinations with ultrasound devices, however, only capture snapshots of the respective condition and require frequent visits to doctors, especially in high-risk pregnancies. With the help of novel wearables and smart textiles, researchers in the EU-funded project Newlife aim to enable continuous obstetric monitoring in everyday life.

One goal of the consortium, consisting of 25 partners, is the development of a biocompatible, stretchable, and flexible patch to monitor the progress of the pregnancy and the embryo. Similar to a band-aid, the patch will be applied to the pregnant person’s skin, continuously recording vital data using miniaturized sensors (e.g., ultrasound) and transmitting it via Bluetooth.

For some time now, modern medical technology has been relying on smart textiles and intelligent wearables to offer patients convenient, continuous monitoring at home instead of stationary surveillance. At the Fraunhofer Institute for Reliability and Microelectronics IZM, a team led by Christine Kallmayer is bringing this technology to application-oriented implementation, benefitting from the Fraunhofer IZM’s years of experience with integrating technologies into flexible materials. For the integrated patch, the researchers are using thermoplastic polyurethane as base materials, in which electronics and sensors are embedded. This ensures that the wearing experience is similar to that of a regular band-aid instead of a rigid film.

To ensure that the obstetric monitoring is imperceptible and comfortable for both pregnant individuals and the unborn child, the project consortium plans to integrate innovative MEMS-based ultrasound sensors directly into the PU material. The miniaturized sensors are meant to record data through direct skin contact. Stretchable conductors made of TPU material tracks will then transmit the information to the electronic evaluation unit and finally to a wireless interface, allowing doctors and midwives to view all relevant data in an app. In addition to ultrasound, the researchers are planning to integrate additional sensors such as microphones, temperature sensors, and electrodes.

Even after birth, the new integration technology can be of great benefit to medical technology: With further demonstrators, the Newlife team plans to enable the monitoring of newborns. Sensors for continuous ECG, respiration monitoring, and infrared spectroscopy to observe brain activity will be integrated into the soft textile of a baby bodysuit and a cap. "Especially for premature infants and newborns with health risks, remote monitoring is a useful alternative to hospitalization and wired monitoring. For this purpose, we must guarantee an unprecedented level of comfort provided by the ultra-thin smart textiles: no electronics should be noticeable. Additionally, the entire module has to be extremely reliable, as the smart textiles should easily withstand washing cycles," explains Christine Kallmayer, project manager at Fraunhofer IZM.

For external monitoring of the baby's well-being, the project is also researching ways to use camera data and sensor technology in the baby's bed. Once the hardware basis of the patch, the textile electronics, and the sensor bed is built and tested, the project partners will take another step forward. Through cloud-based solutions, AI and machine learning will be used to simplify the implementation for medical staff and ensure the highest level of data security.

The Newlife project is coordinated by Philips Electronics Nederland B.V. and will run until the end of 2025. It is funded by the European Union under the Horizon Europe program as part of Key Digital Technologies Joint Undertaking under grant number 101095792 with a total of 18.7 million euros.

ALTENPFLEGE 2022: Intelligently equipped rooms for more independence in old age

Most people want to live as independently as possible in old age. Exhibitors at the industry's leading trade fair ALTENPFLEGE from April 26 to 28 in Essen, Germany will be showing how senior facilities with modern interior design and smart equipment meet this need.

Demand for forms of housing such as service living is on the rise. Studies predict a need for around 540,000 new service living units in the coming years. One of the major trends at this year's 32nd edition of the Altenpflege trade fair is how senior facilities are meeting the rapidly growing demand with flexible room design and digital support. They can be seen in the Aveneo special show, including intelligent systems for stove shut-off, lighting control and room temperature, as well as for fall sensors and emergency calls.

Future tenants or buyers of serviced apartments are prepared to invest specifically in their own living environment (source: Terragon study 2021). The focus is on a feel-good atmosphere, a high level of security and the option of using care services if required. "This can be facilitated by a cleverly thought-out arrangement of the rooms within a serviced apartment, for example by arranging the bathroom and bedroom right next to each other and making the wall with the washbasin rotatable," explains Carolin Pauly, managing director of Universal Rooms, which considers itself to be the interface between the wishes of the operators and the products in the serviced apartment market. "The furniture and furnishings industry is called upon to design modern collections with hidden product features that make life easier in old age," Pauly demands. This could be, for example, a grab handle built into the washbasin or a dining table that can be accessed by a wheelchair.

Lighting management also plays an important role. It should convey a sense of well-being and security as well as provide orientation and safety. Age-related clinical pictures in particular place high demands on lighting. Here, lighting systems that simulate the natural day and night rhythm can provide help.

Living, care and digitalization combined
The Chief Executive Officer of the Evangelische Heimstiftung (EHS - Evangelical Home Foundation), Bernhard Schneider, sees "an individually and comfortably furnished apartment that uses intelligent technology to provide a great deal of security and self-determination" as the senior living of the future. "I am certain: In the future, in a sector-free setting, we will have to understand housing, nursing and care, and digitalization even more strongly as building blocks that can be combined as needed."

According to Schneider, this starts with housing: In a nursing apartment or an assisted living apartment, in a shared apartment or other form of communal living, in a residence or an intergenerational project. All forms of housing should be well integrated into the neighborhood - this requires reliable, financed advisory structures, for example through neighborhood managers. In addition, there is care, support and assistance, in the form of day or night care, a mobile service or volunteers. "And technology, for example through our Aladien system, i.e. with intelligent home emergency call, fall sensors, stove shut-off, roller shutters and light control, video door telephony, etc. In the future, Aladien will evolve into a service robot," predicts Schneider.

This makes it possible for people to live a self-determined life and participate in society, even in old age. That's what people want, he says: a pleasant living environment, social contacts, cultural offerings and the certainty that someone will take care of them if necessary. "What we need for this is political commitment in the form of an ambitious funding program for modern forms of housing in old age," demands the EHS CEO. This would not only help the older generation, but young families could also benefit because this would free up the far too spacious apartments and terraced houses of the older generation for them.


ALTENPFLEGE – Trade fair and congress for the care industry since 1990
The traditional leading trade show for the care industry has so far been held alternately in Hanover and Nuremberg. From this year it alternates between Essen and Nuremberg. It covers all segments of professional geriatric care: services and products for care and therapy, occupation and education, IT and management, nutrition and home economics, textiles and hygiene as well as space and technology. In more than 30 lecture blocks, the accompanying trade congress covers the current topics of the industry, such as digitalization, the future of professional nursing care, hospice and palliative care, training or the new collectively agreed payment under the Healthcare Development Act (Gesundheitsversorgungsweiterentwicklungsgesetz - GVWG).
