Pressure sensing pad, method of making the same, pressure sensing system, and pressure map display

摘要

A pressure sensing pad or mat comprises a piezoresistive layer, a top electrically conductive layer comprising a plurality of electrically conductive top strips extending in a first direction along one side of the piezoresistive layer, a bottom electrically conductive layer comprising a plurality of electrically conductive bottom strips extending in a second direction, nonparallel to the first direction, along the other side of the piezoresistive layer, and top and bottom adhesive layers holding the top and bottom strips against the piezoresistive layer so as to inhibit relative displacement of the strips relative to the piezoresistive layer and relative to each other. Also disclosed are a method of manufacturing the pressure sensor pad, a pressure sensing system that employs the a sensor mat, and a pressure map display for displaying a pressure distribution of an object resting on the pressure sensing mat.
