  • Capacitor for measuring forces
    Patent number: 4370697
    Abstract: A capacitor comprising at least two electrodes separated from one another by an elastic dielectric for measuring forces acting upon one of the electrodes--the so-called measuring electrode--by detecting the resultant change in capacitance. The dielectric comprises a web having at least at one face thereof protruding nap-shaped protuberances defining a hollow space which is at a reduced pressure in relation to the external pressure.
    Type: Grant
    Filed: November 3, 1980
    Date of Patent: January 25, 1983
    Assignee: Semperit AG
    Inventors: Rainer Haberl, Josef Kastner
  • Force measuring capacitor
    Patent number: 4266263
    Abstract: A capacitor comprising at least two electrodes separated from one another by an elastic dielectric formed of rubber and/or plastic for measuring forces acting upon one of the electrodes--the so-called measuring electrodes--by detecting the resultant change in capacitance. The dielectric in its unloaded state is pre-compressed and preferably possesses a number of hollow spaces.
