The temperature difference between body heat and ambient air is sufficient to provide power with the help of a very small voltage converter.German Fraunhofer Institute has developed a tiny voltage converters, which together with a thermo generator can generate 4 mW at 2 ° C temperature difference .. The 1.5 x 1.5 mm high-voltage converter can generate voltages up to 3.3 volts. The efficiency varies depending on load and input voltage of between 30 and 80 percent.
 The converter is 1.5 mm per side
