In recent years, the new vibration monitoring methods using distributed continuous sensors have been actively developed in the field of smart sensors and actuators. PVDF film sensors have been mainly used for such purposes because they are less expensive and easy to handle. A lot of techniques have been reported so far, but they are not available for the structures whose boundary conditions are unknown. The authors propose the new approach using the PVDF films with the shape of appropriate Fourier series, which is applicable to the structure of arbitrary boundary conditions. Identification of the mode shape is simulated in the case of cantilever beam, which shows the availability of the proposed method. Furthermore, the experiment was carried out with the cantilever-like plate. The good agreements were obtained when compared with the calculated results.
