Hand prostheses that restore tactile sensitivity to amputees. Sensors capable of detecting diseases prior to outbreaks. These applications could soon become part of conventional treatment thanks to microchips implanted in the body. At Fraunhofer IZM, the Technologies for Bioelectronics working group is busy developing ultra-thin biocompatible coatings for bioelectronics implants. The core aim is to enable decade-long functionality of miniature implants without the need for surgical interventions.
