Enhanced Quarter Spherical Acoustic Energy Harvester Based on Dual Helmholtz Resonators
An enhanced quarter-spherical acoustic energy harvester (AEH) with dual Helmholtz resonators was designed in this work. Compared with the previous research, this AEH can harvest multi-directional acoustic energy, has a widened resonance frequency band, and has an improved energy conversion efficienc...
