The comb drive actuator with segmented electrodes is fabricated for realizing the large displacement. The counter torque generated by applying the higher driving voltage at a segmented electrode can suppress the instability, called "side snap-over". The stable travel is confirmed to extend by 4-6μm. The obtained maximum displacement is 50μm.
