Abstract

We produced a new metal-core piezoelectric fiber by means of both hydrothermal and extrusion methods. The insertion of a metal core was significant in view of its strength—greater than that of ceramic materials—and in that electrodes are not required in the fiber's sensor and actuator applications. A new smart board was designed by mounting these piezoelectric fibers on the surface of a CFRP composite, and the sensor and the actuator function were evaluated. We showed that self-sensing was possible using this smart board. And function as a sensor and actuator, this board can control the vibration.
