• 要約等: <p>In order to achieve carbon offsets and the SDGs by 2050, there is a need to reduce CO₂ emissions and advance clean energy creation technologies. In addition to reducing CO₂ emissions, it is crucial that we also reduce the energy we consume in industry, society, and our daily lives in order to lessen our impact on the environmental. In light of this, our study focuses on energy harvesting, which is one of the energy-saving technologies. As part of our research on energy harvesting, we investigated electrical power generation when flow-induced self-excited vibration is generated in a PVDF film in a uniform flow. The generated voltage and current were investigated by installing a rectangular PVDF in a uniform flow and varying the flow velocity. When the PVDF motion in the flow was visualized, it vibrated significantly while maintaining twodimensionality in the spanwise direction. Further, when the self-excited vibration generated a strong upward or downward flow near the downstream edge of the PVDF film was formed.<i><b> </b></i></p>
