Human Body Heat Harvesting via Wearable Biomedical Sensor Generating Renewable Energy

A wearable thermoelectric generator is an innovative method to generate electric power from the heat of human body.This study presents an innovative design and integration of systems, including a ring, thermoelectric generator (TEG), and heat sinks used as power sources in wearable technology.An experimental setup was designed to investigate the performance of the power generation from the proposed system.In addition, the effect of the environmental temperature on the power output of the integrating system was investigated.The key results showed that the integrating system could generate closedcircuit voltage and output power values of about 22 mV and 480 W, respectively, at an ambient temperature of 7.This research demonstrated that the wearable ring with TEG gives a potential route for power generation by harvesting the heat of the human body, which could be used to run the biomedical sensor in the future.
