A galloping-based piezoelectric energy harvester has been proposed to generate power for wireless sensors using low-speed airflow. The utilization rate of wind energy is improved by optimizing the geometric parameters of the bluff body. The energy collection system's distributed parameter mathematical model is established by integrating the electromechanical model and aerodynamic model. To verify the model, a wind tunnel test is carried out. A parametric analysis is conducted to investigate the effects of external resistance, wind speed, and bluff body shape on power. When the wind speed is 5.2 m/s and the resistance is 150 kΩ, the power is 3.72 mW. [ABSTRACT FROM AUTHOR] |
