In order to better utilize the superior transverse and shear piezoelectric properties of 0.23Pb(In1/2Nb1/2O3)–0.45Pb(Mg1/3Nb2/3)O3–0.32PbTiO3 single crystals near the morphotropic phase boundary, a complete set of elastic, dielectric, and piezoelectric coefficients of [1¯ 0 1] poled single crystal were determined by resonance and ultrasonic methods at room temperature. The electromechanical coupling coefficient k32 and transverse piezoelectric coefficient d32 can reach 0.94 and −2073 pC/N, respectively. At the same time, electromechanical coupling coefficient k15 and shear piezoelectric constant d15 are as high as 0.91 and 2526 pC/N. This complete set of material properties will provide convenience for device designs and fundamental theoretical studies such as applications in high-sensitivity medical ultrasonic transducers and large displacement actuators.
