ABSTRACT:
A method and apparatus for electromagnetically rebalancing a micromechanical transducer via a plurality of current carrying electrodes disposed beneath or above the transducer interacting with a current carrying conductor disposed on the transducer. In a first embodiment, the micromechanical transducer comprises a micromechanical accelerometer having electromagnetic rebalance of an asymmetric plate. In an alternative embodiment, the transducer comprises a micromechanical gyroscope having electromagnetic driving of an outer gimbal and electromagnetic rebalance of a sense gimbal.
