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. Such pressure sensors can be included in fingerprint authentication subsystems including associated integrated electronic circuitry (e.g., encryption, image processing, fingerprint matching, communication and/or location determination circuitry). Such subsystems can be included in various access control systems (e.g., smart cards and mobile electronics). Unpackaged IC chips can be included on the flexible substrate or can be disposed on a separate electronics substrate attached to the sensor.
