Abstract

We investigate both analytically and experimentally the sensitivity and activity of functionally graded piezoelectric devices under electromechanical loading. A phenomenological model of domain wall motion in alternating current (ac) electric fields is used, and a nonlinear finite element analysis is employed to discuss the effects of electromechanical loading, number of layers, and property gradation on the induced voltage, deflection and internal stresses for the cantilever sensors and actuators. Experimental results, which verify the model, are also presented using functionally graded piezoelectric bimorphs. Good agreement is obtained between the tests and predictions.
