Various transverse length extensional modes of single crystal piezoelectrics were evaluated for high power capabilities and compared with the longitudinal "33" mode. Both bar and tube geometries, and d 31 and d32 piezoelectric modes were explored. The elastic, piezoelectric and dielectric properties were evaluated under dynamic conditions using a matrix of stress, temperature and electric field conditions. Cristallographic orientation significantly affected domain stability; poling along the 〈001〉 axis showed a higher phase transition point, relative to stress and temperature, than the 〈110〉 orientation. The optimized transverse mode (d31) showed significantly improved properties due to the orthogonal relationship between electric field and pre-stress; strains over 0.2% were recorded.
