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

Abstract

The electromechanical responses of multicomponent solid solutions Pb 0:95 Ba 0:05 (Mg 1=3 Nb 2=3 ) 0:471 (Zn 1=3 Nb 2=3 ) 0:102 (Ni 1=3 Nb 2=3 ) 0:152 Ti 0:275 O 3 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 d 33 reach 1600 m/V at very low values of the electric field (…5 kV/cm). The observed features of the electromechanical responses of the studied ceramics are advantages in terms of their possible application in actuators.
