ABSTRACT:
A piezoelectric actuator includes a pair of piezoelectric members which are oriented to shear laterally toward each other in the presence of an applied voltage. A hinge having translational members (which act similarly to a rack) and a rotating member (which acts similarly to a pinion) is attached to the top of the piezoelectric members with one translational attached to a respective one of the piezoelectric members. A driven member attached radially outward from the rotating member will then move through an arc when the piezoelectric members laterally shear. An object, such as a mirror, when carried by the distal end of the driven member, will then be actuated.
