Thermoelectric generators played a major role in this experiment.

An experimentator has used waste heat of his body to turn humans into batteries. Nick Zetta, who runs Basically Homeless YouTube channel, turned himself into a battery using thermoelectric generators.

Zetta followed a simple approach that aimed at capturing the waste heat from the human body and turning that into electricity.

Thermoelectric generator, which uses temperature differential to force electron flow, played a major role in this experiment. The device generates electricity when one side is hotter than the other side.
