Development of a “smart patch” that prevents sweating in clothes

Scientists have developed a new smart material that prevents the spread of stains resulting from perspiration on clothes.
The material, developed by experts from Duke University in the US, includes a series of small holes that open to allow heat to escape when a person begins to sweat, and which close again to retain heat once dry.
The developers of the material confirmed in their study published on the “Science Advances” website that because it is lightweight, it uses physics instead of electronics to open its slots, likely to act as a “patch” that is placed on different types of clothing to help make the wearer more comfortable in different temperatures.
When compared to average traditional textiles, the smart material is 16 percent warmer when dry with the openings closed, and 14 percent cooler when wet with the openings open.

“People who ski or hike in cold weather usually wear layers so they can adjust the amount of heat their clothing traps as their body temperature rises, but By strategically placing patches of a material that can release heat when a person sweats, one can imagine creating a one-size-fits-all.”
Hsu confirmed that he and his scientific team want to “vent the sweaty parts of the body such as the chest and back, not necessarily the armpit area.”
Hsu and his team did not mention the price of the patch when it was put on the market, or the cost of manufacturing it.
