New York : If sweating is your problem with workout, Massachusetts Institute of Technology (MIT) researchers have a new solution to offer. They have designed a breathable workout suit that can keep the body cool and dry in the gym.The workout suit has ventilating flaps that open and close in response to the body's heat and sweat, and can make one feel like, in the words of one of the researchers, wearing an "air conditioner" on the back.

Powered by harmless microbes built into the fabric, these flaps, which range from thumbnail- to finger-sized, shrink and expand in response to changes in humidity. "This work is an example of harnessing the power of biology to design new materials and devices and achieve new functions," said Xuanhe Zhao, Associate Professor in the Department of Mechanical Engineering and study co-author.

The microbial cells act as tiny sensors and actuators, driving the flaps to open when an athlete works up a sweat, and pulling them closed when the body has cooled off, the researchers described in a paper published in the journal Science Advances.The paper also describes a running shoe with an inner layer of similar cell-lined flaps to air out and wick away moisture. In trials to test the running suit, study participants donned the garment and worked out on exercise treadmills and bicycles while researchers monitored their temperature and humidity using small sensors positioned across their backs.
