A Study on the Fabrication and the Properties of Piezoelectric Actuator
압전 액츄에이터의 제작 및 그 특성에 관한 연구
Abstract
In this paper, the single round type and the multilayered type actuator using PZT powders were manufactured and their piezoelectric, displacement and time response characteristics were investigated. In the single round type actuator, the piezoelectric coefficient and the displacement increased with sintering temperature. In the multilayered actuator, the piezoelectric coefficient and the displacement increased with the layered number. In ten layered case, the piezoelectric coefficient and the displacement were higher over three times and six times than those of the single round type, respectively. At the voltage applied, the response velocity of the multilayered type was higher over two times than that of the single round type.
