4Natural Acidity Detector Opera
4 NADO - natural acidity detector opera
How could living systems and technology lead designer-maker to explore symbiotic poetry, non-human musicality, and uncontrolled performance?
This experimental and bio-art project is investigating the proprieties of the Physarum Polycephalum, also known as slime mold, and understand a potential relationship with technology such as arduino. A symbiosis bertween living organism, technoloogy and humans is the purpose of this exploratory journey through biology, music and coding.
Physarum Polycephalum, literally the «many-headed slime», is a yellow to deep reddish orange slime mold that is sensitive to light. PP. polycephalum is one of the easiest eukaryotic organism (not a bacteria) to grow in culture and has been used as a model organism for many studies involving slime perculiar movement and cellular motility.
Slime mold can act as a bio-indicator by changing of colour depending of the pH.
Slime mold is a conductible living system and so can conduct electricity.
Slime mold can act as a memristor (memory + resistance proprieties).
Slime mold grows about 1cm per hour in all direction, looking for food.
Thanks to its sentiivity to appellants and repellants, looking for the most direct and safer way to food source, slime mold can "solve" maze.
Slime mold is highly sensitive to light, and so, can act like a light sensor.
Here the sound sample created thanks to arduino. By connecting the slime mold to the circuit, this uncontrolled concert happened.
Project developed at MA Material Futures, Central Saint Martins.
