ABSTRACT:
A motion sensor is provided for sensing motion or acceleration of a body, such as an accelerometer for use in an on-board automotive safety control system or navigational system. The motion sensor is a piezoresistive motion sensor that operates in a closed loop force rebalance mode. As such, the motion sensor may be considered a hybrid of piezoresistive sensors and capacitive force rebalance sensors. The sensor achieves this novel combination through a mechanically-biased proof mass that enables-the use of a single electrode for maintaining the proof mass in a null position during the operation of the sensor.
