Fraunhofer FEP, ISIT Develop Metal-Coated Polymer Films for Affordable Biosensors

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP and the Fraunhofer Institute for Silicon Technology ISIT have successfully developed and tested flexible electrochemical biosensors on metallized film substrates.

Fraunhofer FEP has the technology to provide polymer films with a thin metal layer, which is based on a roll-to-roll process. A high degree of uniformity of the layer‘s thickness and a lack of defects represent particular technological challenges in this manufacturing process.

The growing market for wearable devices requires a high number of small, lightweight and high capacity sensors for different applications in sport, medicine or at work. Especially useful are so-called “wearables” such as functional wristbands, which provide practical assistance while barely being felt.

These devices can monitor body function and provide valuable information. In addition, the electronics should adhere flexibly to the arm.
