This paper deals with active vibration control of flexible structure by high-polymer piezoelectric films, which is based on the concept of smart structure. At first, characteristics and problems of active vibration control method using piezoelectric materials as sensor and actuator are discussed. Then, the concept of distributed vibration control method is introduced and several examples from the author's studies are shown. Included in the topics are vibration control experiments of cantilever beams using rectangular-shaped sensor/actuator pairs, vibration control experiments of simply supported beams using triangular sensor/actuator pair, wave absorbing control of cantilever beams using two pairs of triangular sensor/actuator, vibration control experiments of cantilever beams and circular rings by a self-sensing actuator using piezoelectric films of different thickness. Finally, an overview of this study toward the future is presented.
