摘要： A sheet film protective covering for different types of contour sensing devices is described. In a preferred embodiment, this covering is a mylar sheet film that is coated with a layer of a conductive material. The bottom surface of the mylar film is also preferably coated with a layer of an adhesive. The sheet film covering preferably is contiguous and serves the purpose, among other things, to protect the underlying surface of the pressure-sensing device from contaminants and from electrostatic discharge, as well provide force concentration during use.

摘要： A sensor for a textured surface (e.g., a fingerprint) is provided. The sensor includes a flexible substrate and a flexible membrane supported above the substrate by one or more spacers. The sensor also includes multiple pressure sensor elements responsive to a separation between parts of the membrane and corresponding parts of the substrate. The membrane is conformable to the textured surface being sensed, so the variation in separation between substrate and membrane is representative of the textured surface being sensed. A preferred sensor array arrangement has a set of parallel substrate electrodes on the substrate facing the membrane and a set of parallel membrane electrodes on the membrane facing the substrate, where the substrate and membrane electrodes are perpendicular. The sensor array is preferably an entirely passive structure including no active electrical devices, to reduce cost. Row and column addressing circuitry can be provided as separate units (e.g., ASIC chips) to be hybrid integrated with the sensor array.
