Wearable Keyboard Using Conducting Polymer Electrodes on Textiles

Abstract

A wearable keyboard is demonstrated in which conducting polymer electrodes on a knitted textile sense tactile input as changes in capacitance. The use of a knitted textile as a substrate endows stretchability and compatibility to large-area formats, paving the way for a new type of wearable human-machine interface.

Keywords: conducting polymers; human-machine interfaces; stretchable electronics; textiles; wearable electronics.
