New workout suit by MIT breathes out body’s heat, sweat
MIT scientists have designed an exercise suit with breathable ventilation valves that open and close in response to the heat and sweat of an athlete. These components, ranging from the thumbnail image to the size of the fingers align with the microbial cells that shrink and grow in response to changes in living moisture.
The cells act as sensors and small actuators, causing the fins to open when athlete sweat and retains when the body cools.
Researchers have also fabricated a running shoe with an inner layer similar to the flaps of the cells to get out of the air humidity and discharge. Moisture sensitive cells require no additional elements to detect and respond to moisture. The microbial cells they use have also been found to be safe to touch and even to consume.
In the study published in the journal Advances Science, researchers designed moisture-sensitive cells not only to pull open blinds, but also illuminated in response to moisture conditions.
“We can combine our cells with genetic tools to introduce other characteristics of these living cells,” said Wen Wang, a former Massachusetts Institute of Technology (MIT) scientist in the United States.
“We use fluorescence as an example, which allows people to know it again in the dark. In the future, we can combine the aroma release capabilities through genetic engineering. So maybe after after having done The gym, the shirt can release a pleasant odor to the smell, “Wang said.
The researchers first worked with the most common non-pathogenic E. coli strain, which has been shown to swell and shrink in response to changes in moisture.
We then designed the cells to express the green fluorescent protein, which allows the cell to glow when it detects moisture conditions. It then uses a cell printing method that previously developed for E. coli printing on the rough and natural latex sheets.
The team printed parallel lines of E. coli cells on the latex sheets, creating two-layer structures and exposing the tissue to changing wet conditions.
When the tissue was placed on a heating plate for drying, the cells began to reduce, which caused the surface layer of latex to curl. When the tissue is then exposed to vapor, the cells began to glow and expand, causing the elasticity of the latex.
After undergoing 100 wet / dry cycles, Wang said that the fabric had “no dramatic deterioration” either in its cell layer or in its overall performance.
The researchers worked on bio-cloth in a portable garment design of a racing suit with latex fins stamped cells on the back of the suit lined up.
“People may think that heat and sweat are the same, but in fact, some areas like the lower spine produce a lot of sweat, but not a lot of heat,” said Yao Liner, a former student Graduated from MIT.
