Flexible and stretchable electronics offer a wide variety of wearable electronics applications such as electronic-skins and healthcare/medical devices. Among various conductive materials for wearable electronics, carbon nanotube (CNT) thin films are advantageous in flexibility/stretchability, conductivity, and transparency. In addition, CNT thin films can be used both as a channel material for high-performance transistors and as a metallic conductor for interconnections; i.e. integrated circuits can be constructed by fully using CNT thin films. A stretchability is one of essential functions for the wearable devices which are able to be directly attached to body. In this work, we have realized stretchable and transparent all-carbon devices.
