We have successfully manufactured rubber-like large-area stretchable integrated circuits comprising printed elastic conductors and organic active components including transistors, and developed two applications; One is stretchable active matrix organic light-emitting diodes displays and the other is stretchable electromagnetic interference (EMI) measurement sheet that can detect EMI distribution on the surface of electronic devices by wrapping the devices in the sheet. The stretchable devices can spread over arbitrary surfaces including free-formed curvatures and movable parts, thereby significantly increasing the applications of electrical circuits.
