Energy harvesting from the ambient wireless signals has grown recently in the field of self-sustained and autonomous sensor networks. This technique needs to design specific antenna to receive ambient power within corresponding frequency band, which extremely extend the design cycle. In addition, the available power in the low-frequency bands under 100 MHz is a good power source for energy harvesting. But there is less energy harvesting investigation focused on this frequency band due to the requirement of larger antenna. In this paper, we use HFSS simulation platform to investigate the feasibility of using human body as a monopole antenna for energy harvesting in the frequency range of 10–100 MHz. The detailed measurements carried out in a general electromagnetic environment showed that there is about −57dBm power can be harvested (received) by using human body as a monopole antenna without any other electronic components.
