Thin Film Piezoelectric Actuators with Nonuniform Thickness for Reducing Actuating Shear Stress Concentration
Source abstract
Abstract
We show that the actuating shear stress under a thin film piezoelectric actuator can be modulated by varying the film thickness, and that this effect can be used to reduce the shear stress concentration near the actuator edges while keeping the actuating effectiveness.
