Organic transistors on fiber: a first step towards electronic textiles

Abstract

For the first time, we demonstrate flexible transistors formed directly on fibers. This represents a significant step towards the realization of electronics textiles. Fiber transistors exhibit mobilities of >10/sup -2/ cm/sup 2//V-s measured at 20 V V/sub DD/. The entire transistor is fabricated without resorting to conventional lithography techniques. Patterning is achieved via shadowing from overwoven fibers. The process is compatible with textile manufacturing, and is therefore a promising technology for scalable e-textile fabrication.
