Dl. Devoe et Ap. Pisano, MODELING AND OPTIMAL-DESIGN OF PIEZOELECTRIC CANTILEVER MICROACTUATORS, Journal of microelectromechanical systems, 6(3), 1997, pp. 266-270
A novel model is described for predicting the static behavior of a pie
zoelectric cantilever actuator with an arbitrary configuration of elas
tic and piezoelectric layers, The model is compared to deflection meas
urements obtained from 500-mu m-long ZnO cantilever actuators fabricat
ed by surface micromachining, Modeled and experimental results demonst
rate the utility of the model for optimizing device design, A discussi
on of design considerations and optimization of device performance is
presented.
