CAPACITIVE NODE MEASUREMENT IN A CAPACITIVE MATRIX PRESSURE TRANSDUCER
摘要
<p>A method and system for measuring the distribution of pressure forces over a selected area includes a sensor having an array of pressure sensing capacitance nodes formed by intersecting rows and columns, where measured capacitance of a node is compared to a fixed value of reference capacitance placed on each row that can be measured as if it was another node.</p>
