Abstract

A woven fabric having at least three layers disposed on top of one another. One layer forms a lowermost woven fabric layer and another layer forms an uppermost woven fabric layer. A first and a second woven layer have electrically conductive warp threads and/or electrically conductive weft threads. An intermediate layer is disposed between the first woven fabric layer and the second woven fabric layer. The first woven fabric layer, the second woven fabric layer, and the intermediate layer form a sensor arrangement which has an electrical property that varies while a force acts on the layers. Each of the uppermost and lowermost woven fabric layer in terms of weaving technology is connected to one of the other woven fabric layers present.
