Abstract

The piezoelectric, elastic and dielectric properties of PMN-PT single crystals have been evaluated for performance in high power, high duty cycle naval applications. Alternative crystal orientations, maintain high piezoelectric properties (d31 ∼ -1000 pC/N), and allow for high height/width aspect ratio and the application of the prestress perpendicular to the poling direction. Modification of the composition of PMN-PT showed a 50-75% decrease in the low temperature (< 50°C) dependence of the dielectric constant. The coupling remained high (k33> 0.8), and one-dimensional modeling showed only a 1-8 dB drop in the source level relative to PMN-30%PT. This is an improvement as compared to state-of-the-art, by allowing a higher drive field as a result of increased temperature stability and a higher mechanical Q.
