en.Wedoany.com Reported - German FILK Freiberg Institute and OUT e.V., with support from Covestro, have developed a flexible conductive polyurethane film, advancing the field of smart textiles. Funded by the German Federal Ministry for Economic Affairs and Energy, the research combines conductivity with flexibility by incorporating carbon nanotubes into water-based Impranil® polyurethane dispersions.

This flexible conductive polyurethane film creates a uniform conductive "potential field" through laser structuring, allowing LEDs and sensors to be freely distributed on the textile surface without traditional wiring. The technology supports real-time monitoring and bidirectional communication, offering new possibilities for wearable devices.

Dr. Martin Heise from the FILK Institute stated: "Our goal is to rethink how electronic components are integrated into textiles. By using Covestro's Impranil® polyurethane dispersions to create conductive surfaces instead of fixed wiring, we can distribute sensors and light sources more freely." Dr. Iris Vela-Wallenschus from OUT e.V. noted that this technology achieves a level of precision that is difficult to reach with traditional wiring.

The platform has a wide range of applications, such as phototherapy baby clothing for neonatal jaundice, integrating blue light LEDs and sensors into the garment to regulate phototherapy in real time. Additionally, it can be used for heated textiles, pressure sensors, and more. Dr. Torsten Pohl, Global Head of Textile Coatings at Covestro, emphasized that the platform based on this flexible conductive polyurethane film is scalable, with Impranil® providing key flexibility and durability.
