  • Method and device for measuring a physical variable
    Patent number: 6324910
    Abstract: A method for measuring a physical variable in which a structure is put in resonant oscillations and a change in the oscillation frequency of the structure as a result of a change in the physical variable to be measured is detected, and a frequency-analog signal is provided. A structure oscillating with a resonance frequency receives an electrostatic force.

  • Force sensor having an adjustable distance between an operating point and a point of mechanical instability
    Patent number: 6012341
    Abstract: A force sensor, especially an acceleration sensor or a pressure sensor, has a structure that vibrates in resonance, and its oscillation frequency is variable due to an acting force which is to be detected. The distance of an operating point of the force sensor from the point of its mechanical instability can be adjusted by applying an electric voltage.
