The developed AEH (DAEH) consists of two Helmholtz cavities (HCs) and a commercially available piezoelement. The HCs were fabricated from Teflon material using conventional machining operations. An indigenous test bench for in-lab characterization of DAEH has also been developed. Various experiments were performed to experimentally record the frequency response function, loading and power characteristics. Additionally, the in-lab and open-air characterization of the DAEH is also reported. Furthermore, the proposed prototype of DAEH is compared on the basis of various benchmarks with the prototypes available in the literature. The experimental results indicate a maximum power density of 32.7 μW/cm 3 at 130 dB.

The prototype is capable to charge a fully discharged lithium ion battery in one and half hours using simple human body motions The proposed prototype has novelty in terms of its ability to generate power in a wide bandwidth. This provides a continuous power supply even at low body motions
