Human Body Energy Harvesting Thermogenerator for Sensing Applications

Abstract

A low temperature thermal energy harvesting system to supply power to wireless sensing modules is introduced. The thermoelectric generator module (TEG) makes use of the temperature gradient between the human body (the heat source) and the ambient to deliver a low voltage output that is up-converted by means of a power management circuit. This regulated power source is able to reliably supply a wireless communication module that transmits the collected temperature, current and voltage measurements.
