Abstract
The electromechanical field concentrations due to surface and internal electrodes in multilayer piezoelectric film actuators are investigated through numerical and experimental characterization. A nonlinear finite element analysis is carried out to discuss the effects of electric field and poling on the displacement and internal electromechanical fields in fully and partially poled piezoelectric actuators, by introducing models for polarization switching. Displacement measurements are also performed for the actuators, and a comparison of the predictions with experimental data is conducted.
