Energy harvesting of the human body via piezoelectric & thermoelectric principles

Abstract

This research aims to delve into energy alternatives for biomedical applications by utilizing waste energy from our bodies. The focus of this study is based on two types of energy harvesting: Piezoelectric and Thermoelectric generators. The findings of this investigation showcase an average voltage generation per step of the PEG of 52.3mV and a TEG voltage average of 7.89V @ΔT<10°C. Even so, the applications of the designed circuits are restricted by their low current generation. For that matter, the contributions of this investigation are intended to serve as a stepping-stone for future developments in human energy harvesting for biomedical applications.
