| It uses as the only power source the body temperature and drives with that an electric oscillator. The difference of the body to the environment temperature just can generates some millivolt. But with some tricks and some High Tech one can convert these and an astable multivibrator can be powered with that. It will oscillate in a audible range depending on the setting and with a connected headphone one can listen to the sound.\\ | It uses as the only power source the body temperature and drives with that an electric oscillator.
