PZT actuator

A high precision displacement-measuring interferometer based on a phase modulation technique was developed. A PZT actuator was utilized to drive a mirror of a Michelson interferometer by applying a sinusoidal voltage to the PZT controller.

Piezoelectric materials form the backbone of several components utilized in communication systems, defense systems, industrial automation, medical diagnostics, energy storage and harvesting, and information technology. In high performance piezoelectric applications the material of choice is based upon lead-based composition with Pb(Zr,Ti)O3 (PZT) being the base. Recently worldwide environmental considerations are demanding the elimination of lead-based materials from all the consumer items. This has created urgency for finding alternative to PZT.
