Low- and high-field electromechanical responses of relaxor-based multicomponent ceramics for application in multiregime actuators

Abstract

The electromechanical responses of multicomponent solid solutions [Formula: see text][Formula: see text]([Formula: see text][Formula: see text])[Formula: see text]([Formula: see text][Formula: see text])[Formula: see text]([Formula: see text][Formula: see text])[Formula: see text][Formula: see text]O3 in low and high electric fields were studied. In both cases, significant electromechanical responses are observed. In particular, the maximum values of the large-signal piezoelectric coefficient [Formula: see text] reach 1600[Formula: see text]m/V at very low values of the electric field ([Formula: see text]5[Formula: see text]kV/cm). The observed features of the electromechanical responses of the studied ceramics are advantages in terms of their possible application in actuators.
