Based on the torsion dynamics theory  the technique and relative formula are presented for analyzing the actuating voltage and the switching time  on which the effect of the air squeeze film damping is already considered. The optimized results of the structural parameters are compared between this technique and the finite element modeling (FEM). The optimized result of parameters is as: length  width and thickness of the torsion beam are 700  12 and 10m  length and width of the cantilever beam are 1900 and 1000m  length and width of the balance beam are 100 and 1000m  and distance of the upper and lower electrodes is 55m  respectively. The actuating voltage is about 50 V  and the switching time Toff and Ton are about 5 and 12 ms  respectively. The computed results show that the air squeeze film damping is an important factor for the study of dynamic response on micro-actuator. Finally  an optical technique is described for the measurement of the actuating voltage and switching time of the device  and the difference between the experimental results and theoretical datum is discussed.
