To address the low electromechanical conversion footjoy weste herren efficiency associated with traditional single-degree-of-freedom (SDOF) piezoelectric energy harvesters, this study proposes a two-degree-of-freedom (2-DOF) cut-out piezoelectric beam for wind-induced vibration energy harvesting.Experimental comparisons conducted on four bluff bodies indicated that the triangular column exhibits superior aerodynamic stability, achieving an output voltage of 11.6 V at a wind speed of 7.

0 m/s.Furthermore, the cut-out piezoelectric beam demonstrated a 1.9-fold increase in output voltage compared to its non-cut-out counterpart.

These results underscore the potential of the 2-DOF cut-out piezoelectric beam veuve ambal rose design as an autonomous power solution for IoT nodes operating in complex environments.
