Abstract

Piezoelectric actuators and sensors have been widely applied in various fields, such as high-precision positioning, micromanipulation. However, it's hard to neither install both actuators and sensors in a narrow space nor apply them to compact structure devices. In this paper, a novel self-sensing piezoelectric actuator based on structural integration is therefore proposed to meet the needs of industrial development. A piezoelectric stack is using to output force and displacement, and quartz crustal is used as a force sensing unit. A prototype was fabricated and tested. The maximum output displacement of the actuator is about 28.84 μm when drove by a maximum voltage of 150 V. The results indicate that the actuator proposed in this paper has functions of piezoelectric actuator and force sensor.
