The quest for portable water solutions has taken a remarkable turn with the development of a jacket that can harvest drinking water directly from the air. This innovation, spearheaded by engineers at The University of Texas at Austinpromises to revolutionize water access for a wide range of users, from outdoor enthusiasts to those in water-stressed regions.
The jacket incorporates a specialized textile that collects moisture from the air and channels it to detachable harvesting units. These units, when heated, produce drinkable water, offering a novel approach to atmospheric water harvesting. This technology could be a game-changer for anyone who spends time in areas with limited access to clean drinking water.
The Science Behind the Innovation
The textile used in the jacket is engineered with amphiphilic hydroxypropyl cellulose fibers combined with a salt called LiCIwhich efficiently pulls water from the air. This moisture is then transferred to detachable harvesting units built into the jacket. These units are placed in a foldable collector piece and heated to produce water.
During tests, the jacket yielded between 400 and 900 milliliters of drinkable water per day, depending on humidity levels. This represents a significant improvement over conventional water-harvesting materials, which often require bulky devices or large systems. The researchers focused on the fibers themselves, overcoming a common challenge in the field.
Applications Beyond Clothing
The potential applications of this technology extend far beyond clothing. The researchers envision incorporating the textile into backpacks, tents, emergency sheltersand other outdoor gear. This could allow everyday items to help collect water from the air, providing a decentralized water solution for remote communities, emergency response situations, and water-scarce regions.
Discovery to Impact, the University’s research commercialization unit, has filed a patent application for the technology. The team is also exploring the use of this innovation in outdoor activities, remote field operations, disaster response, and water access in arid or infrastructure-limited regions.
Real-World Potential
This breakthrough comes alongside another significant achievement from the same research team. They developed a solar water-harvesting device that pulled a record amount of drinking water from the air in both the Chihuahuan Desert of New Mexico and the more humid environment of Austin, Texas. In tests, the device captured 1.3 liters of clean water per day in both arid and semi-humid areas, demonstrating the real-world potential to address drinking water shortages.
The device is part of the team’s broader AirGel invention, which won the top prize in the graduate category of the 2026 National Collegiate Inventors Competition. At the center of the device is a specially engineered hydrogel fabric made from biomass-derived materials. This fabric absorbs moisture from the air and releases it when heated by sunlight, allowing the water to be condensed and collected.
The regions where the device should perform best overlap with many of the world’s most water-stressed areas, including parts of North Africa, the Middle East, South Asia, and sub-Saharan Africa. This makes the technology especially promising as a decentralized water solution for remote communities and emergency response settings where conventional water systems are difficult to build or maintain.
