en.Wedoany.com Reported - An engineering team at the University of Texas at Austin has developed a smart jacket capable of extracting drinking water directly from the air.

The findings have been published in the journal Science Advances. The team utilized a material called "Hierarchical Open-Porous Fiber (HOP-Fiber)," transforming traditional static water extraction devices into a wearable form, opening a new direction for personal portable water collection.

The textile material inside the jacket actively captures water vapor from the air and transports the moisture to detachable water collection units. These units are placed in a foldable collection device, and after heat treatment, they produce water that is directly drinkable.

Experimental data show that in environments with relative humidity ranging from 20% to 80%, the textile material can produce 3.76 to 7.45 liters of water per kilogram per day. The actual recovered water volume ranges from 410 ml to 894 ml per day, equivalent to approximately 400 to 900 ml of drinking water daily.

The team conducted outdoor tests in the arid region of Xichang, China; the semi-arid region of Austin, USA; and the humid region of Chengdu, China. In the arid environment, 410 ml of water samples were collected daily, with low lithium ion residues in the collected water, meeting the World Health Organization's drinking water standards.

The paper notes that the fabric can withstand deformations such as curling, folding, and twisting, and its potential applications extend beyond clothing to include backpacks, tents, and emergency shelters.
