  • Fully decoupled lateral axis gyroscope with thickness-insensitive Z-axis spring and symmetric teeter totter sensing element
    Patent number: 8689632
    Abstract: A micro-electromechanical systems (MEMS) transducer (400) is adapted to use lateral axis vibration of the drive mass (210) to generate non-planar oscillations of a coupling mass (220) in response to Coriolis forces created from in-plane rotation, which in turn generate non-planar motions of a symmetric teeter-totter sense mass (230) which are detected as a capacitive difference signal by capacitive electrodes (403, 404) formed on the substrate (402) below the sense mass (230).
