Abstract:
A micro-electromechanical systems (MEMS) transducer (100, 700) is adapted to use lateral axis vibration to generate non-planar oscillations in a pair of teeter-totter sense mass structures (120/140, 720/730) in response to rotational movement of the transducer about the rotation axis (170, 770) with sense electrodes connected to add pickups (e.g., 102/107, 802/807) diagonally from the pair of sense mass structures to cancel out signals associated with rotation vibration.
