Stretchable and Robust Transistor of Single Wall Carbon Nanotube, Gel and Elastomeric Materials

We have developed the coating and microfabrication technique of the single walled carbon nanotubes and its composite with rubbers in the way compatible to the conventional device technology in order to incorporate the unique properties of SWCNTs, such as diversity of electrical properties depending on the charity, mechanical flexibility and stretchability arising from the formation of network structure, with device applications. Utilizing the process technologies, we have recently succeeded in assembling the field effect transistor of all rubbery materials on the rubber substrate, demonstrating that it exhibits the transistor performance comparable to the conventional CNT-transistors and significant tolerance to the mechanical loadings. The stretchability and robustness of our FET is promising for the wearable electronics, especially which is used for human body.
