Analysis of Skin-Worn Thermoelectric Generators for Body Heat Energy Harvesting to Power Wearable Devices.

The rapid growth of wearable electronic devices motivates investigation of powering such devices using energy harvesting, with the long-term goal of continuous operation without the need to recharge or replace batteries. In this work, we present a study conducted using a wearable device to measure the voltage, power, and energy that can be harvested continuously from human body heat using a thermoelectric generator (TEG) worn on the skin surface. Using a TEG worn on the arm, we demonstrate an average of 22.
