Abstract

The dependence of k k31eff on the aspect ratio G= l1 / l2 has been calculated for resonators made of [001] poled 0.67Pb (Mg 1/3Nb2/3) O3 -0.33 PbTiO3 (PMN-0.33PT) and [011] poled 0.71Pb (Mg1/3 Nb2/3) O3 -0.29 PbTiO3 (PMN-0.29PT). Based on the derived unified formula, the lateral electromechanical energy conversion efficiency k 31 eff 2 decreases with G for [001] poled PMN-0.33PT but increases with G for [011] poled PMN-0.29PT.
