**6. Conclusions**

In this study, a novel type of piezoelectric energy harvester was developed based on the principle of wind-induced galloping. The dynamic model of the fluid–structure interaction system was established, and CFD techniques in conjunction with the Newmarkβ method were adopted to obtain corresponding numerical solutions. Wind tunnel tests were also conducted to detail the working performance of the harvester. The main findings and conclusions are summarized below:
