MIT’s Moisture-responsive Workout Suit Keeps Athletes Comfortable

Here is a moisture responsive workout suit designed to keep athletes comfortable. It is lined with live microbial cells that shrink and expand in response to changes in humidity. It requires no additional components for sensing humidity.

These cells act as sensors and actuators, opening the flaps as athletes sweat and close them as the body cools off. Here is how this works:

After five minutes of exercise, the suit’s flaps started opening up, right around the time when participants reported feeling warm and sweaty. According to sensor readings, the flaps effectively removed sweat from the body and lowered skin temperature, more so than when participants wore a similar running suit with nonfunctional flaps.

The researchers are planning to commercialize this tech in collaboration with sportswear companies.
