Piezoelectric materials are the most widely used functional materials for sensor and actuator applications in smart structural systems. This paper introduces the development of piezoelectric fibers with a metal core, which can be used as an electrode. When the other electrode is coated on the outer surface of the fiber by sputtering or using conductive paste, a single fiber can be used as a sensor or an actuator. Due to its small diameter, fiber can easily be integrated into structural materials without significant influence on their strength. The sensor and actuator functions of the fibers were confirmed after they were bonded to a composite beam. Experiments on the integration of piezoelectric fibers with a composite board were also performed. Anew application of piezoelectric fibers in air flow sensors was also proposed.
