EPFL researchers have developed films with conductive tracks just several hundreds of nanometers thick that can be bent and stretched up to four times their original length. They could be used in artificial skin, connected clothing, and on-body sensors.Instead of bring printed on a board, the tracks are almost as flexible as rubber and can be stretched up to four times their original length and in all directions a million times without cracking or interrupting their conductivity. The material could be used to make circuits that can be twisted and stretched — ideal for artificial skin on prosthetics or robotic machines.
