  • Patent number: 7805994
    Abstract: The present invention relates to a novel silicon micromechanical gyroscope, which is used in control technology field to measure pose measurement of a rotating body, such as aerobat, motor tire and drilling platform, wherein the novel silicon micromechanical gyroscope main includes a sensing element and a signal process circuit. The sensing element further comprises a silicon slice frame, a silicon slice, an upper electrode ceramics plate and a bottom electrode ceramics plate. The signal process circuit further comprises a signal detecting bridge circuit used as bridge arm of the capacitor sensing element, and a SCM signal process circuit with data process module. The novel silicon micromechanical gyroscope is able to replace a drive force from the drive conformation with a rotating force from the rotation of the rotating body so as to achieve a novel silicon micromechanical gyroscope without a drive conformation.
