摘要

The goal of this research is to design and evaluate a mutlilayer bender actuator, on a concept that each ceramic layer has different value of piezoelectric d_(31) coefficient. By stacking the ceramic layers with the different piezoelectric d_(31) coefficient, the internal stress within the actuator body became maximized. Three type actuators (called as sample 1, 2 and 3) were presented in a specification of stacking ceramic layers with low and high piezoelectric properties. Sample 1 was actuator with high piezoelectricity (d_(31) = -210 pC/N), Sample 2 with low and high piezoelectricities (d_(31) = -100 and -210 pC/N)), and Sample 3 with low piezoelectricity (d_(31) = -100 pC/N). Sample 2 exhibited higher displacement than the other samples under application of a voltage over 50 V, due to higher internal stress between the top and bottom layers. In addition, high generative force can be expected at the multilayer structure actuator, sample 2, with the two piezoelectric components over actuator with one component.
