| Abstract: | A piezoelectric bender with trilayer structure was fabricated.Piezoelectric ceramics PZT-5H were used as piezoelectric layers on both sides,and Be-Cu as the elastic interlayer.The characteristics of piezoelectric bender,including the output displacement,the displacement hysteresis loop,creep and the basic frequency were investigated by laser distance measuring instrument LC-2400A and LV-1610.The relations between the thickness of piezoelectric layers and elastic layer and its static and dynamic characterist... |
