This paper describes the results of our numerical and experimental studies of the electromechanical field concentrations due to surface and internal electrodes in partially poled multilayer piezoelectric film actuators under electric fields. A nonlinear finite element analysis is performed to predict the polarization switching zone and to discuss the electromechanical fields. Displacement versus voltage curves are also measured to validate the numerical predictions, and comparisons are made between numerical results and experimental data. Moreover, the results of the partially poled multilayer actuators are compared with those of fully poled actuators.
