The piezoelectric vibration energy harvesting has higher conversion efficiency and output voltage. The piezoelectric energy harvester has a significant study value for MEMS systems and portable devices. From the research, avoiding the reattachment of vortexes and increasing the pressure difference between the objects could effectively improve the vibration performance. This paper proposes a curved plate with a tail design, expected to have higher vibration frequency and larger amplitude at the galloping phenomenon. The design has been compared with a curved plate design by simulation, showing better performance. Its average lift coefficient increases by 57.42% within wind speed 1-10m/s compared to the curved plate design.
