    Abstract: A pressure sensor (20) includes a test cell (32) and sense cell (34). The sense cell (34) includes an electrode (42) formed on a substrate (30) and a sense diaphragm (68) spaced apart from the electrode (42) to produce a sense cavity (64). The test cell (32) includes an electrode (40) formed on the substrate (30) and a test diaphragm (70) spaced apart from the electrode (40) to produce a test cavity (66). Both of the cells (32, 34) are sensitive to pressure (36).However, a critical dimension (76) of the sense diaphragm (68) is less than a critical dimension (80) of the test diaphragm (70) so that the test cell (32) has greater sensitivity (142) to pressure (36) than the sense cell (34). Parameters (100) measured at the test cell (32) are utilized to estimate a sensitivity (138) of the sense cell (34).

    Abstract: An electronic ink cartridge includes, in a direction of a central axis within a cylindrical body, a core body extended out from a distal end of the cylindrical body, a coupling member disposed on a side of a proximal end of the cylindrical body, a coil housed between the core body and the coupling member and having a predetermined inductance, and a pressure sensitive element whose capacitance changes according to pressure applied to the core body. Two terminals of the coil are electrically connected respectively to two terminals of the pressure sensitive element to thereby form two terminals of a resonance circuit formed by the coil and the pressure sensitive element. A connecting terminal electrically connected to at least one of the two terminals of the resonance circuit is disposed on a proximal end surface side of the coupling member to be accessible thereon from outside.

    Abstract: A force or pressure transducer is includes a substrate, a dielectric material disposed on the substrate, a spacing member disposed on the dielectric material, and a resilient element disposed on both the dielectric material and the spacing member. A portion of the resilient element is separated from the dielectric material, and another portion of the resilient element is in contact with the dielectric material. The contact area between the resilient element and the dielectric material varies in response to movement of the resilient element. Changes in the contact area alter the capacitance of the transducer, which can be measured through associated circuitry.

    Abstract: A passive, non-contact radio frequency (RF) strain sensor changes resonant frequency as it is deformed. The sensor's resonant frequency can be determined by monitoring the signals transmitted and/or reflected therefrom upon illumination of the sensor by a known RF signal source. The sensor can be implemented using thin film techniques on a flexible thin substrate that can be attached to the surface of a structural member of interest.
