Meter scale touch sensor fabricated with weaving technique

Abstract

We reports on the fabrication and characterization of meter-scaletouch sensors. For the applications to wearable keyboards and bedsensors for elders, large area touch sensors are inevitable, butconventional MEMS force sensors are not suitable because of theirsmall area. Therefore, we developed the techniques to coat conductivepolymer on long fibers and weave fibers, forming large area sensors.The capacitive type touch sensors have been constructed with wovensensor fabric. The area of the fabric covers 1 meter-square.
