Piezoelectric linear actuator


An actuator that uses piezoelectric elements to generate linear motion.

The piezoelectric elements are used to develop various linear actuators due to their advantage of the high thrust force and quick response, despite of the small displacement. In Scanning Probe Microscope (SPM), displacements of a stacked piezoelectric element are directly used for high resolution positioning. To make strokes longer, various methods are studied, for instance, inchworm mechanism.
