Optoelectronic micropositioning device with a piezoceramic transducer

摘要

This paper presents an experimental study on the behavior of piezoceramics type PZT, having a high compliance, and their application for an optoelectronic micropositioner device with piezoceramic transducer. The piezoelectric ceramics are crystallite conglomerate ferroelectrics materials with random orienting. In the laboratory we have realized PZT ceramics with various additions (Ni, Bi, Mn), presenting high compliance, for optoelectronic micropositioning device in micrometry displacements. The experimental transducers, realized like stacks of 30 $DIV 35 pieces of PZT thin disks, supplied with 0 $DIV 1000 V voltages, have produced 0 $DIV 15 $mu@m displacements.
