A dual-stage servo system using enhanced active-passive hybrid piezoelectric actuators has been developed for improving existing dual-stage piezoelectric actuators for higher precision positioning and shock resistance, due to the incorporation of passive damping in the design. In this paper, an assembled suspension with three different configurations of microactuators is investigated via shock test...
Current dual-stage actuator design uses piezoelectric patches only, without passive damping. In this paper, we propose a dual-stage servo system using enhanced active-passive hybrid piezoelectric actuators. Because they incorporate passive damping, the proposed actuators will improve the existing dual-stage actuators, giving them higher precision and better shock resistance. We report finite-element...
