    摘要: The sensor has at least two membranes of which one membrane is sealed and one other membrane has an opening to ambient pressure, and functions as a reference device. The sealed membrane deflects as function of pressure whereas the deflection of the "open" membrane remains unaltered.
    The reference device enables determination of relevant calibration parameters such as capacitance offset, dC/dP, parasitic capacitance, membrane stiffness, back side pressure. This then enables an accurate capacitance pressure function to be obtained with only two calibration points and without needing to control pressure levels.

    摘要: The invention relates to a token (100), to an integrated circuit (200) comprising the token, to a method of randomizing the token and a system (500, 502) for randomizing the token. The token comprises a physical unclonable function (10, 12, 14, 16, 18) and comprising probing means (110) for probing the physical unclonable function. The physical unclonable function comprises a capacitor (20, 22) comprising a dielectric medium (30, 32) being arranged at least partially between the electrodes (20A, 20C; 22A, 22C) of the capacitor. The dielectric medium is configured for contributing to a capacitance value of the capacitor and comprises conducting particles (40, 42; 40A, 40B, 40C) substantially randomly dispersed in the dielectric medium. The conducting particles comprise a phase changeable material being changeable between a first structural state (40A, 40C) having a first conductivity and a second structural state (40B) having a second conductivity different from the first conductivity.

    摘要: A differential pressure sensor comprises a cavity having a base including a base electrode and a membrane suspended above the base which includes a membrane electrode, wherein the first membrane is sealed with the cavity defined beneath the first membrane. A first pressure input port is coupled to the space above the sealed first membrane. A capacitive read out system is used to measure the capacitance between the base electrode and membrane electrode. An interconnecting channel is between the cavity and a second pressure input port, so that the sensor is responsive to the differential pressure applied to opposite sides of the membrane by the two input ports.
