Abstract:
A pressure sensing device includes a first conversion layer and a second conversion layer, an electrically conductive element between the first and second conversion layers, and a pair of electrically conductive yarns connected to the electrically conductive element, wherein the first and second conversion layers include at least one deformation member adapted to deform the electrically conductive element and change the resistivity of the electrically conductive element, when pressure exerts on the first and/or the second conversion layer.
Abstract:
A process for manufacturing a fabric pressure sensor comprises cutting a sensing fabric to a pre-determined size, connecting a flexible electric wire with a wire of the sensing fabric by sewing, fixing the sensing fabric by means of a clamping positioner at a pre-determined tension, bonding a lower conversion layer with the sensing fabric by means of a lower conversion layer positioning box, bonding an adjustable column with the sensing fabric by means of an upper conversion layer positioning box, and bonding the upper conversion layer with the adjustable column by means of the upper conversion layer positioning box. A tool for manufacturing the sensor comprises an electrical property measuring device, a wire connecting tool, and a sensor structural component assembling tool. The present invention provides an easy and convenient way of manufacturing a fabric pressure sensor, monitoring the quality of manufacture, and enhancing the manufacturing precision and product yield.
