A study on characteristics of piezoelectric fan in PZN-PZ-PT ceramics

PZN-PZ-PT 세라믹스 압전팬의 특성에 관한 연구

In this study, a piezoelectric fan was fabricated using piezoelectric element of 0.13PZN-0.41PZ-0.46PT prepared by extruding method. The sizes of the piezoelectric element and the piezoelectric fan were adjust to utilize commercial ac source(100V, 6OHz). The size of the piezoelectric element was $0.26{\times}19.5{\times}45$mm and the resonant frequency and the electromechanical coupling coefficient were 31.26KHz, 31.58% respectively. The size of the piezoelectric fan was $0.62{\times}19.5{\times}78.5$mm and the maximum displacement was 40mm.
