N2 - The shear piezoelectric behavior of [001] poled tetragonal and [011] poled rhombohedral Pb(In 1/2Nb 1/2)O 3-Pb(Mg 1/3Nb 2/3)O 3-PbTiO 3 (PIN-PMN-PT) crystals, with 1T and 2R domain configurations, respectively, were investigated under uniaxial stress perpendicular to polar direction. The shear piezoelectric coefficient d 15 was found to decrease with increasing compressive stress for both 1T and 2R crystals. Based on thermodynamic analysis, the phase structure can be stabilized by applying compressive stress perpendicular to polar direction, resulting in a harder polarization rotation process, accounts for the reduced shear piezoelectric coefficient. Of particular importance is that the allowable drive electric field was greatly increased and transverse dielectric loss was drastically reduced under compressive stress, leading to the improved maximum-shear-strain.
