Abstract

The transformation of wind energy into low-power electricity using piezoelectric materials enables the possibility of powering wireless electronic components especially in high wind areas. This work thoroughly explores the effect of aspect ratio (length/width) on the performance of inverted flag-based piezoelectric energy harvesters. Wind tunnel experiments are conducted for a range of electrical loads to quantify the optimal power output. Conclusions are drawn regarding the overall dynamics of the multiphysics system for the design and optimization of this new class of scalable wind energy harvesters.
