MIT researchers have invented a new type of workout material that can breathe using biological cells. The project, called bioLogic, is essentially a breathable workout suit covered in small flaps. The flaps are lined with live microbial cells that shrink and expand in response to changes in humidity allowing the entire outfit to act as a reactive sensor to let athletes cool off as needed.
The group released their findings in a new paper.
These cells are so strong that they can induce bending of the substrate they are coated on, said lead author and Wen Wang.
Opening and closing flaps isnt the only thing this system can do.
We use fluorescence as an example, and this can let people know you are running in the dark. In the future we can combine odor-releasing functionalities through genetic engineering. So maybe after going to the gym, the shirt can release a nice-smelling odor, said Wang.
The material uses a nonpathogenic strain of E. coli that could swell and shrink in humidity and even fluoresce when you sweat, glowing green as you exert yourself. From the release:
This suggests you will soon have bioluminescent and bioreactive clothing that can be washed, dried, and worn again. The suit works far better than traditional workout wear and the researchers found that effectively removed sweat from the body and lowered skin temperature when working out. Theyve added the technology to the running shoe which, obviously, will soon allow E. coli to keep your tootsies nice and cool.
