  • Publication number: 20060117857
    Abstract: A force or pressure transducer is disclosed. In one embodiment, the transducer has a substrate, a dielectric material disposed on the substrate, a spacing member disposed on the dielectric material, and a resilient element disposed on the dielectric material and the spacing member. A portion of the resilient element is separated from the dielectric material, and a 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 by circuit means.

  • Publication number: 20050211301
    Abstract: Integrated micro-valve is formed to control fluid flow and pressure. The valve converts supplied energy to mechanical energy through an energy conversion means resident above a flexible wall or membrane. In one embodiment a sealed cavity contains a fluid that expands and contracts as it is heated or cooled, thus causing the flexible wall to move. Movement of this wall or membrane is used to move a valve element and dynamically control the opening or closing of a valve port over a predetermined range. Additional stiffening means are added to the membrane to improve performance.
