발전소자응용을 위한 PMW-PNN-PZT적층 압전세라믹스의 특성

In this study, multilayer piezoelectric ceramics was manufactured using the PMW-PNN-PZT ceramics. Then, their physical characteristics for applicaton of electric power generation were investigated according to the numbers of multilayer. With increasing the numbers of multilayer, effective electromechanical coupling factor($k_{eff}$) and capacitance were decreased and increased, respectively.
