Medical textiles and sensors enhance skin protection in healthcare

Infants in intensive care units are particularly vulnerable to pressure injuries due to prolonged periods of immobility. To address this concern, researchers at Empa, in collaboration with ETH Zurich, the Zurich University of Applied Sciences (ZHAW), and the University Children's Hospital Zurich, are developing a novel pressure-equalizing mattress.

This mattress aims to minimize the risk of tissue damage by distributing pressure evenly across the baby's body. By leveraging advanced pressure sensors and microprocessor-controlled chambers, the mattress adjusts its firmness based on the individual needs of each infant. Initial trials have demonstrated promising results, with a substantial reduction in pressure on sensitive areas compared to traditional foam mattresses.

In another initiative, Empa researchers are focusing on preventing pressure ulcers in adults through the development of smart sensor systems embedded in textiles. These sensors monitor both pressure and oxygen levels in the skin, providing real-time feedback to patients and healthcare providers.

By detecting early signs of tissue damage, these systems enable proactive interventions, such as repositioning, to prevent further injury. This approach not only improves patient outcomes but also reduces healthcare costs associated with treating pressure injuries.

The technology underpinning these innovations includes cutting-edge manufacturing processes, such as microfluidic wet spinning for producing light-conducting polymer fibers. These advancements have led to the development of patented technologies and the emergence of spin-off companies like Sensawear, poised to enhance wearable sensor technology.

Supported by funding schemes like BRIDGE, interdisciplinary teams comprising experts in materials science, optics, electronics, medicine, and technology are driving forward these innovations.

Beyond pressure injury prevention, these technologies hold promise for a wide range of applications in healthcare, paving the way for enhanced patient care and improved quality of life.

By leveraging these medical textiles, healthcare providers can deliver more personalized and proactive care, ultimately leading to better outcomes for patients across various age groups and medical conditions.
