Researchers Develop New Battery-Free Device That Analyzes Sweat.

reports on “a new device — wearable, wireless and battery free,” which “improves the ability to monitor and diagnose health problems by analyzing the sweat on your skin.” The device featured in the journal Science Advances “provides real-time information on the wearer’s pH, sweat rate, and levels of chloride, glucose and lactate — high levels of which could signal cystic fibrosis, diabetes or a lack of oxygen.” The team who developed the device plans to “apply for approval from the Food and Drug Administration.” https://www.nytimes.com/2019/01/18/health/wearable-tech-sweat.html
