Biothermal battery
Biophan Technologies, a US company, has developed the Biothermal battery, based on the use of thermoelectric materials, using nanoscale-based, thin-film materials to convert thermal energy produced naturally by the human body into electrical energy.
The resulting power can be used to 'trickle charge' batteries for medium-power devices such as defibrillators, or directly power low-energy devices like pacemakers.
