A New Smart Ring Uses Finger Sweat to Track Health
Tech > Mobile > Wearables A New Smart Ring Uses Finger Sweat to Track Health Researchers believe they've created the first smart ring to monitor biochemical health measurements like glucose, vitamin C and alcohol levels. But engineers at the University of California, San Diego, believe they have created the first smart ring that uses finger sweat to track chemical biomarkers. The ring is only a prototype, but it shows the potential for future smart rings to continuously monitor the body on a molecular level instead of relying solely on biophysical data.
