Relaxor Ferroelectrics for Electrostrictive Transducer

Abstract

The objective of this program is to investigate the potential of electrostrictive actuator materials for use in NAVY-type sonar. The anticipated performance requirements for such materials is summarized in the following: Operating temperature range 0-30 C; High sensitivity; i.e. large E-field induced strain; Minimal hysteresis and low loss; Frequency of operation; Mechanically stiff (low compliance). Additional requirements include operational E-field strain under prestress, and duty cycles.
