Highly piezoresistive textiles based on a soft conducting charge transfer salt

The integration of smart materials into human wearable interfaces is a current topic of interest. This paper reports the integration into a polyester textile of a bi-layer (BL) film based on a polymeric matrix containing a top-layer of a microcrystalline network of an organic conductor. The resulting textiles, in addition to be conducting, exhibit the excellent strain sensing properties of BL films maintaining at the same time their flexibility.This work was funded by CETEMMSA, the EU EC FP7 ONE-P large-scale collaborative project no. 212311, Marie Curie Est FuMaSSEC, the DGI (Spain) with project EMOCIONa (CTQ2006-06333/BQU), and Generalitat de Catalunya 2009SGR-00516.
