Many studies have investigated the application of wind energy using different harvesters. However, there is little research on the small scale wind energy harvester based on vibration. This paper propose an ocarina-like harvester and investigated the effect of the shape by FEM simulation. The airflow will cause vibration and the mechanical energy of this vibration can be harvested and converted to electrical energy with attached piezoelectric film. The optimal electrical power was obtained using 1 mm lead zirconate titanate (PZT) film with opening size of 8 mm and the corresponding electrical power is 0.574 mW at a constant wind speed of 4 m/s. A potential application of this type of harvester is to construct between the walls of a high-rise building, exposed to high natural wind speed.
