  • Microbridge and cantilever electrostatic actuators are fabricated using thin film technology and surface micromachining at low temperatures (⩽100 °C) on glass substrates. Electrostatic actuation is accomplished by applying a voltage, combining a dc component to a low frequency ac component, between the microstructure and an underlying gate counterelectrode. The movement is optically detected by focusing a laser beam on the top of the structure and monitoring the deviation of the reflected light… CONTINUE READING
