Abstract: A capacitive fingerprint sensor is fabricated on a plastic substrate (363) with an embedded integrated circuit chip (380). The invention describes a way to create two or three dimensional forms for electrode structures (321, 322, 325, 365, 366) that can be used to optimize the performance of the sensor.

Abstract: The invention relates to a method and apparatus for linearizing a flow velocity sensor based on pressure difference measurement. According to the method, a difference of two pressure signals is measured from the flow under measurement and is proportional to the square of the flow velocity. The pressure difference is measured using a micromechanically manufactured symmetrical capacitive differential pressure sensor based on the force balance principle. The pressure-induced deviation from force balance is compensated for by inducing on the pressure-sensing diaphragm of the differential pressure sensor a force-balance-restoring electrostatic pressure. The amplitude of the force-balance-restoring electrical feedback control signal also acts as the system output signal and is directly proportional to the square root of the difference of the two pressure signals, and thus, a linear function of the flow velocity.
