Abstract
The linear actuator [5] is formed from a stack of laminates of piezoelectric or electrostrictive material to provide a large expansion. The height of the stack is limited by placing it on the surface of the substrate [1]. The stack is produced in two sections [2] with a physical gap between them and an electrical interconnection. USE - Micro actuators ADVANTAGE - Simple to produce; low cost.
