    摘要: A MEMS sensor includes a proof mass that is suspended over a substrate. A sense electrode is located on a top surface of the substrate parallel to the proof mass, and forms a capacitor with the proof mass. The sense electrodes have a plurality of slots that provide improved performance for the MEMS sensor. A measured value sensed by the MEMS sensor is determined based on the movement of the proof mass relative to the slotted sense electrode.
