This study aims to establish basic techniques for detecting vibration of flexible structures by using distributed sensors. It is important to establish measuring methods using distributed sensors. This paper shows the sensor shapes and the measuring methods for vibration distribution of a thin plate by using long span PVDF (polyvinylidene fluoride) sensors as distributed sensors. The methods are evaluated by the comparison between experimental results and calculational prediction based on our theory. In a previous study[1], we show the experimental results were in good agreement qualitatively with the values obtained by theoretical calculation. In the present study, we performed precise simulations and experiments, and we obtained quantitatively good agreement between experiments and theoretical calculations. We also predicted the errors in the case of omitting higher-order mode of PVDF shapes.
