Experimental evaluation of the electromechanical properties of relaxor piezoelectric single crystals under stress, thermal, electrical bias conditions is proposed through the use of various dynamic and static evaluation methods. The proposed phase I effort concentrates on evaluation of properties of PMN-PT using resonant bars, and Lumped-Parameter (L-P) dumbbell resonators under pressure loading and temperature biasing conditions.
Benefit: The technology developed will be immediately applicable to acoustic transducers used in civilian commercial systems including imaging, communication, and navigation. The property assessments may be useful for electromechanical sensors and actuators for a broad spectrum of civilian applications including vibration and acoustic energy harvesters.
