Abstract

Rhombohedral phase relaxor-PbTiO ₃ solid solution single crystals poled along [011] _c exhibits superior lateral extensional piezoelectric response, which enables the excitation of a pure low frequency flexural mode with a bridge-type electrode configuration. For the ternary 0.24Pb(In _1/2Nb _1/2) O ₃-0.46Pb(Mg _1/3Nb _2/3)O ₃-0.30PbTiO ₃ single crystal poled along [011] _c, the electromechanical coupling factor of the flexural mode reached as high as 0.66, and the resonance frequency of this mode can be easily made in kHz range, making it possible to fabricate very small size low frequency sensors and actuators. We have delineated theoretically the coupling between flexural mode and other modes and realized a strong pure flexure mode.
