摘要：
A high-performance wind-induced vibration energy harvester with an angle section head is designed. Experimental results show that the harvester has a wide frequency-locked/operating wind speed range. Experiments are carried out for the harvester with different angles and lengths of the angle section head. It is found that the reasonable design of the angle section head can benefit wind energy harvesting. In this study, the widest operating wind speed range of 13.4 m/s (from 6.6 m/s to 20 m/s) is experimentally demonstrated, and the maximum output power is 214.6 mu W.
