Abstract

Wind energy has potential and usefulness as natural energy, and can be harvested from wide range of windy area. We have developed a flexible piezoelectric device (FPED) composed of polyvinylidene fluoride (PVDF) and functional resin. The characteristics of the FPED are thin layer, light and flexible. Therefore, both a force caused by breeze and flow energy with various frequency spectrums can be harvested effectively using the FPED. In this study, we made clear electrical characteristics of the FPED and availability of an attached bluff body in uniform flow. Moreover, we validated electrical efficiency of the FPED which is laminated with a stretching resin and has a roughness surface such as woolen and small hemisphere.
