Single crystal naval transducer development

Recently discovered families of piezoelectric Lead Magnesium Niobate/Lead Titariate (PMN-PT) and Lead Zinc Niobate/Lead Titanate (PZN-PT) single crystal materials have generated great interest in the Navy sonar community because of their high 33-mode coupling factor and large saturation strain, thereby potentially allowing sonar transducers with greatly increased bandwidth and power density. The Naval Undersea Warfare Center (NUWC) is developing a prototype single crystal high power sonar transducer for potential naval applications. In addition to progress on the transducer development, measurements on the single crystal materials are presented.
