Collaborative research project by PUMA + MIT Design Lab, powered by Biorealize.

Carbon Eaters are microbially-activated stickers that respond to the CO2 in the environment by changing color to inform their users about the quality of air around them. As the user performs their daily run, the organisms begin to change color from dark yellow-brown to bright purple. More carbon dioxide absorption causes more purple, indicating poorer air quality.
