 The Symbiotic Synth is a low voltage oscillator that is powered as well as controlled by the human body, thus an audible bio-feedback can be made possible.\\ The Symbiotic Synth is a low voltage oscillator that is powered as well as controlled by the human body, thus an audible bio-feedback can be made possible.\\
-It was invented and designed by [[http://​wolfgang-spahn.de/​doku.php|Wolfgang Spahn]] ​for the workshop [[http://​shared-habitats.eu/​i-machine-and-energy-harvesting/​|I,​ Machine, and Energy Harvesting]] by Mindaugas Gapševičius and Wolfgang Spahn as part of the exhibition [[http://​shared-habitats.eu/​|Shared Habitats]] in MO Museum, Vilnius, Lithuania in May 2019.\\+It was invented and designed by [[http://​wolfgang-spahn.de/​doku.php|Wolfgang Spahn]] ​and was first presented at the workshop [[http://​shared-habitats.eu/​i-machine-and-energy-harvesting/​|I,​ Machine, and Energy Harvesting]] by Mindaugas Gapševičius and Wolfgang Spahn as part of the exhibition [[http://​shared-habitats.eu/​|Shared Habitats]] in MO Museum, Vilnius, Lithuania in May 2019.\\

-The Symbiotic Synth 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 can generates some tiny little bits of electric power - the so called [[https://​en.wikipedia.org/​wiki/​Thermoelectric_effect|Seebeck Effect]]. With some tricks and high tech in form of the Small Energy Harvesting Chip: [[https://​www.analog.com/​media/​en/​technical-documentation/​data-sheets/​LTC3108.pdf|LTC 3108]] one can convert that small amount of energy into some decent voltage and an [[https://​www.electronics-tutorials.ws/​waveforms/​astable.html|astable multivibrator]] circuit can be powered with that. It will oscillate in a audible range depending on the setting of the potentiometer. And because the headphone are actually part of the oscillation circuit one can listen to the sound, too.\\+The Symbiotic Synth uses as the only power source the body temperature and drives with that an electric oscillator.

 In attaching some sensors, like: light, pressure, skin and temperature depending resistors to the circuit one can have variations of the sound based on the human body and its functions. The generated sound will change depending on breath, heart beat, skin resistance and body temperature.\\ In attaching some sensors, like: light, pressure, skin and temperature depending resistors to the circuit one can have variations of the sound based on the human body and its functions.

-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.\\+With all that both is possible: to power and to modulate a synthesizer with the own human body.
