To address the low electromechanical conversion 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 iphone 11 pro max precio miami 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 design as standoff kingsville ontario an autonomous power solution for IoT nodes operating in complex environments.
