Electricity from body heat

Scientists from the German research centre, the Fraunhofer Institute, have discovered a way to make electricity out of energy from body heat. A circuit of thermo electric generators could produce electricity from temperature differences between the top of the skin and the surroundings. Normally a thermo electric generator can only produce power of 200 mV with the few degrees difference at the top of the skin but thanks to the circuit of thermo electric generators the body heat could produce enough power to run electronic equipment, which is a couple of Volts. Applications named for this technology are products within the medical electronics sector.
