Abstract :
An electrostatic actuation scheme for creating a soft contact is described and applied to cantilevers and doubly clamped beams. The actuation voltage form is composed of a high voltage pulse with a low DC voltage. The voltage pulse height and duration is mapped for achieving minimum impact force, and the results are well predicted by the simulation. Furthermore, a new phenomenon is observed for clamped beams that pulse longer than the soft-landing requirement bounces the beam back rather than stick.
