Weave Patterned Organic Transistors on Fiber for E-Textiles

Flexible transistors were formed directly on fibers in a novel weave-masking fabrication process. Pentacene fiber transistors exhibit mobilities of >0.5 cm/sup 2//V-s measured at 20 V V/sub DD/ and operate stably under a wide range of flexion stress. Devices are defined and positioned solely by a weaving pattern, meaning that simple circuits could potentially be directly built into fabric during manufacturing. This development offers a novel approach for providing information routing within fabric, which is currently a major hurdle in electronic textile development.
