Energy harvesting techniques using piezoelectric materials have been rapidly developed in the world. In our previous work, one kind of kinetic energy harvester using a piezoelectric material was proposed and developed; the harvester was called Flexible Piezoelectric Device (FPED). The FPED was applied to wave and current energy, wind energy and vibration energy. In this study, improving the FPED, a new type of wind energy harvester was proposed and developed to generate electric power from broad band of wind conditions, especially low wind and breeze. The energy harvester consists of a piezoelectric material and a thin soft material, which is Flexible Piezoelectric Sheet (FPS) for wind energy harvesting. The theoretical approach was provided using a classical modal analysis technique. The electric performance of the FPS in several wind conditions was revealed and some important design parameters of the FPS were shown based on experimental results.
