Strain properties of single round type piezoelectric actuator according to sintering temperature

소결온도에 따른 단판형 압전 엑츄에이타의 변위 특성

In this studies, variation of the sintering temperature with a single round type piezoelectric actuator of PZT 401 powder [UPI CO.] were fabricated. The piezoelectric properties were investigated as specimens with sintering temperature $1000^{\circ}C,\;1100^{\circ}C,\;1200^{\circ}C,\;1270^{\circ}C,\;1300^{\circ}C$. The strain was measured with respect to the variation of the electric field(500V-1000V), time, temperature($18^{\circ}C-40^{\circ}C$) and humidity(35%-93%).
