WRIGHT-PATTERSON AIR FORCE BASE, Ohio - A collaborative effort between the Air Force Research Laboratory and industry partners through the Nano-Bio Manufacturing Consortium has led to the development of next-generation wearable patches that can detect electrolyte levels present in human sweat. Using novel AFRL-developed sensor materials and microfluidic technology, the patches can measure sodium and potassium levels present in sweat and transmit this information wirelessly for scientific analysis. The patches will augment research on hydration with the goal of improving human performance in heat or high-stress conditions. (Courtesy photo/GE Global Research)
