Study of Capacitance in Electrostatic Comb-Drive Actuators

While parallel-plate capacitor generate sensing and actuation across planer electrode facing each other, a different class of capacitors take advantage of capacitance generated from sidewalls of electrodes. Such capacitors provide alternative fabrication and operation modes compared with parallel-plate capacitors.

Basic MEMS Actuators

Note that F pp is always attractive and is nonlinear in not only the voltage, but also in the gap between the parallel plates. This geometric nonlinearity makes control of actuators difficult and led to the development of comb capacitors [].SEM images of a comb drive array are shown in Fig. 2 b capacitors are arrays of interdigitated fingers.

Advantages and functions of ceramic capacitors

ceramic capacitors is a capacitor that uses ceramic materials as a medium, coats a layer of metal film on the ceramic surface, and then sinters at a high temperature as an electrode. It is usually used in high-stability oscillating loops as loops, bypass capacitors and pad capacitors. As long as the ceramic capacitor is aimed at high frequency, the high voltage ceramic …
