Characterization of conductive polymer coated silicone elastomer contact structure for woven electronic textile

This paper presents an innovation and fabrication process of electrical contact structure in flexible device technology. A coating of poly(3,4-ethylenedioxythiophene) poly(4-styrenesulfonate) as a solid electrolytic layer deposited on silicone elastomer structure is employed in composing the electrical circuit through a large area of woven electronic textile (e-textile), and functions as the electrical contact between weft and warp (interlaced) fiber ribbons. From the resistance measurements using flexible sheets by weaving polyethylene terephthalate ribbon cable, the structure enhances the durability, flexibility and stability of electrical contact in the woven e-textile better than those of the ribbons without it.
