AI Customer ServiceThe sensing capacitors are formed by the movable seismic mass and the fixed electrodes placed nearby. According to the signal processing schemes, the silicon capacitive accelerometers are usually classified into two major categories: the open-loop accelerometer and the force-balanced accelerometer (i.e., the close-looped accelerometer).
Although a capacitive accelerometer can be made to sense accelerations in either the in-plane or the out-of-plane directions, the in-plane direction is often used because it is easier to integrate interdigitated fingers that increase the capacitance, and thus the sensitivity of the sensor.
The mechanical structures of silicon capacitive accelerometers are basically beam-mass structures just like those for piezoresistive accelerometers. However, the movement of the seismic mass is detected by the capacitance of a sensing capacitor or the differential capacitance of a pair of sensing capacitors.
