Smart ring tracks health via sweat
A team of engineers from the University of California, San Diego, has developed a smart ring that employs osmosis technology to continuously analyze sweat, measuring vital indicators such as glucose, ketones, lactate, vitamin C, and uric acid. The device aims to provide ongoing, accurate health assessments, particularly for diabetes management, by tracking both glucose and ketone levels to determine insulin doses more precisely. The ring uses sweat samples without requiring exercise and automatically calibrates based on individual factors, with calibration stability lasting for two months. Experiments have shown that its performance is comparable to or better than current continuous monitoring devices, offering greater comfort and ease of use. This innovation contributes to improved personalized healthcare and facilitates painless, continuous health monitoring.
