| + | 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, the [[https://www.analog.com/media/en/technical-documentation/data-sheets/LTC3108.pdf|LTC 3108]] one can convert that small amount of voltage into some decent one and an [[https://www.electronics-tutorials.ws/waveforms/astable.html|astable multivibrator]] can be powered with that. It will oscillate in a audible range depending on the setting. And because the headphone are actually a part of the oscillation circuit one can listen to the sound, too.\\ | ||

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.\\ | + | With all that both is possible to power and to modulate a synthesizer with the own human body. And because the generated sound will stimulate the body function, too, the Symbiotic Synth can be called an self-sufficient audio biofeedback device.\\ |
