Developed by the MIT’s Tangible Media Group, this remarkable clothing uses microorganisms to sense perspiration and heat, changing shape to let your body breath on demand. As a bonus, the bacteria employed are fueled by breaking down proteins your body expels while sweating.

Bacillus Subtilis natto bacteria react to atmospheric moisture, expanding and contracting in response to humidity and heat. A specially printed biofilm is overlaid on a spandex suit as shown in the video above.

The special cells sense changes on the body, curling up and thus allowing more airflow when things heat up. MIT is now printing billions of these and testing various applications. “In the era where biology is the new interface, we are imagining a world where actuators and sensors can be grown rather than manufactured,”
