Effect of AC Poling on PIN-PMN-PT Single Crystals for Acoustic Sensors
Abstract
Ternary relaxor-PT single crystals are promising for many naval devices. Further enhancing piezoelectric properties has been difficult, yet critical to achieving the next generation naval devices. In this project, AC poling domain engineering method is investigated to increase dielectric and piezoelectric properties as well as phase transition temperature and coercive field of ternary relaxor-PT single crystals. AC poling domain engineering study, including preparation of PIN-PMN-PT single crystal samples with different compositions and different crystal growth methods, property measurements, domain characterization methods and reliability of AC poling will be extensively investigated in this project. The expected results will enable more efficient and more reliable naval acoustic sensing, acoustic transmitting, and energy harvesting from ambient environment.
