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.
