In an attempt to develop piezoelectric sensors and actuators for smart boards, complex piezoelectric fibers with metal core were fabricated by hydrothermal method. The insertion of metal core was significant in view that the fragility of ceramics can be overcome and electrodes are not required in the use as sensors and actuators. In order to evaluate the sensing and actuating abilities of these new-type fibers, a cantilever structure was constructed by embedding the fiber into the surface layer of CFRP composite board. As a result of a vibration test of this CFRP board by an electromagnetic vibrator, it was found that the fiber has an obvious sensor function, since electric charge was output from the fiber in proportion to the vibration amplitude. On the contrary, it is also evident that the fiber can function as actuators, since the CFRP board was vibrated by applying an AC voltage between the metal core and CFRP matrix.
