  • Patent number: 9404748
    Abstract: An apparatus for driving and sensing motion in a gyroscope including a dielectric mass, an anchor, a spring coupled between the anchor and the dielectric mass, a substrate adjacent the dielectric mass, an insulator layer on the substrate, and a first electrode and a second electrode on the insulator layer. When an alternating current voltage is applied between the first and second electrodes, an electric field gradient is generated in the dielectric mass and causes the dielectric mass to move relative to the anchor. When the dielectric mass has motion relative to the anchor and a voltage is applied between the first and second electrodes, the movement of the dielectric mass generates a current at the first and second electrodes proportional to the motion.

  • Patent number: 9347839
    Abstract: A measuring element formed of a piezoelectric crystal of symmetry class 32 for measuring a force Fz, which acts perpendicularly on the plane x-y and causes a charge accumulation on surfaces of the plane x-y. Applications are measurements in which the transverse forces Fxy orthogonal to the force Fz, which generate an error signal at the measuring element, are expected on the measuring body. The measuring element includes at least four identical measuring element segments having straight edges. In the x-y plane the segments are arranged side by side and spaced apart by narrow gaps at the edges. Together, the segments form the shape of a disc or perforated disc for reducing the interference signals caused by the transverse forces Fxy on the measuring element. The crystal orientations in the x-y plane of all segments are oriented in the same direction or orthogonal to each other.
