Title:
容量マトリックス圧力変換器における容量ノード測定
Document Type and Number:
Japanese Patent JP2009534673
Kind Code:
A
Abstract:
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.
