Displacement Properties of a Multilayer Piezoelectric Actuator with number of Layer

적층형 압전 액츄에이터의 적층 변화에 따른 변위 특성

In this study, displacement values according to variation of laminated layer in piezoelectric body were measured. Samples were $40{\times}12[mm^2]$ and number of printed layer were varied from 3, 5, 7, 9, up to 11. Effect of printed layer variation on displacement properties of multilayer piezoelectric actuator was investigated. Also displacement values were estimated using Atila simulation tool. Difference in measured values and simulation results were compared.
