We see many products that are waterproof but bioengineers at the University of California, Davis are developed a new fabric that can form excess sweat into droplets that drain away. In other words this could lead to fabric that is actually “sweat proof.” The new textile microfluidic platform utilizes hydrophilic (water-attracting) threads stitched into a highly water-repellent fabric, which can literally suck droplets of water from one side of the fabric, propel those droplets along the threads and expel them from the other side. This in turn could leave the fabric dry against the skin. Video after the jump
