Abstract
A torsional electrostatic combdrive with increased stiffness is disclosed. The torsional electrostatic combdrive includes a movable combteeth group, a stationary combteeth group, and a stationary link group. The stiffness of the torsional electrostatic combdrive is increased by coupling the stationary link group to the stationary combteeth group. Advantageously, the present invention promotes reduced gaps of engaging combteeth, increased snap-in voltage of combteeth, and reduced driving voltage of the combdrive.
