While the majority of the literature in energy harvesting is dedicated to resonant harvesters, non-resonantharvesters, especially those that use turbulence-induced vibration to generate energy, have not been studied inas much detail primarily due to their comparatively small power output, general non-tunability and diffculty inassociating ow conditions to harvester behavior. In this extensive study, we look at the behavior of piezoelectriccantilever beams in different types of grid turbulence with the intention of identifying trends in the harvesteroutput. Our results show that the power-law decay of the harvester output that had previously been observedfor rectangular grids holds for a wide variety of fractal grids as well. Additionally, experimental data showsthat the average harvester output in grid turbulence follows a power-law growth with respect to the mean owvelocity for relative short and stiff piezoelectric beams.
