Abstract
Pull-in study of an electrostatic microactuator is essential for making the electrostatic actuation more effective. In this paper, pull-in analysis is presented for an electrostatic torsion microactuator. The torsion microact uator can be used as a microtorsion mirror. A polynomial algebraic equation for the pull-in voltage and pull-in angle of a torsion microactuator is de rived, Two types of microactuators fabricated using bulk micromachining are presented. Measurements done on the fabricated microactuators are reported , showing deviations within 1% error from the calculations. [325].
