摘要

A purpose-built inkjet printing system was used to deposit conductors onto textiles using several hundred printing cycles over a pattern. Conducting polymer [poly(3,4-ethylenedioxythiophene), PEDOT] piezoresistive strain sensors and silver connecting lines were printed onto woven nylon fabric. The conductor fully penetrated the fabric thickness and formed a superficial layer. Silver's high conductivity ensures that most of the resistance change occurs in the PEDOT—localized strain can then be determined. Initial straining cracks the surface PEDOT layer and the response to subsequent strain cycles then becomes reproducible. The resistance change with fabric strain showed a large negative gauge factor attributed to improved contact between yarn fibers when the fabric is strained. This system was used to monitor human joints using fabric sensors taped to the skin.
