ELECTROCONDUCTIVE WOVEN FABRIC, AND TOUCH SENSOR DEVICE BY USING ELECTROCONDUCTIVE WOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To achieve a flexible and low cost electroconductive woven fabric capable of sensing pressure in a high sensitivity, also to provide the electroconductive woven fabric having a woven structure easily detecting a touching position, and a touch sensor device including a signal detection circuit suitable for the structure of the electroconductive woven fabric and using the electroconductive woven fabric as the touch sensor.

SOLUTION: The electroconductive woven fabric 10 includes a spacial configuration that an electroconductive upper cloth 20 and an electroconductive lower cloth 22 woven with electroconductive yarns 12 are overlapped vertically and linked with pile yarns. Either one side of warp yarns and weft yarns forming each of the electroconductive clothes 20, 22 is provided by having a constitution that an electroconductive yarn region 16 obtained by aligning the electroconductive yarns 12 and an insulating yarn region 18 obtained by aligning an insulating yarns 14 are aligned alternately, and the other side yarns have a constitution of aligning only the insulating yarns. By overlapping each of the electroconductive clothes in the direction of crossing the electroconductive yarns 12 with each other so as to function a cell 24 which is a zone of crossing the electroconductive yarn regions 16, as the touch sensor.
