Abstract:
In this paper, we report a promising approach for fabricating large-scale flexible and stretchable electronics using a semiconductor-enriched carbon nanotube solution. Uniform semiconducting nanotube networks with superb electrical properties mobility of approx. 20 cm2 V-1 s-1 and IONIOFF of approx. 104 are obtained on polyimide substrates. The substrate is made stretchable by laser cutting a honeycomb mesh structure, which combined with nanotube-network transistors enables highly robust conformal electronic devices with minimal device-to-device stochastic variations. The utility of this device concept is demonstrated by fabricating an active-matrix back-plane 12 x 8 pixels, physical size of 6 x 42 for pressure mapping using a pressure sensitive rubber as the sensor element.
