Abstract
An amplifier mechanism which utilizes the electroexpansion characteristics of a pair of piezoelectric stack motors pivotally mounted in a rigid frame to directly contact and move with the output actuator element of the mechanism. The stack motors are mounted in opposition in a saggital arrangement so as to provide counterbalanced lateral forces that are manifested in longitudinal amplified movement of the output actuator element.
