Paper Abstract

The comb actuator deformed by microloading effect in DRIE process generally has í«Lí» shape comb electrodes. Therefore, the actuator shows nonlinear differential driving characteristics. A simple modeling is suggested and simulated to explain the driving characteristics. For modeling convenience, the damaged comb electrode is assumed to be a simple í«Lí» shape. According to the modeling, the resonant frequency is estimated to increase as the bias voltage increases. The static displacement curve shows í«Sí» shape.
