The response of a polysilicon parallel-plate electrostatic actuator to a.c. signals at different bias voltages has been measured with a laser interferometer. Using microhinges, large plates (with areas from 100 "am 2 to = 0.1 mm 2) with long thin support beams (such as 600 ~m X 3 ,am ร 1.5 ,am) are
