Medical XpressNew Wearable Ring Tracks Glucose, Ketone and Other Biomarkers in Sweat Simultaneously

✅ Clinical Decision Support / Validated Tool

UC San Diego researchers developed a smart ring capable of continuously measuring up to four biochemical markers from sweat simultaneously. In early testing, glucose measurements tracked commercial continuous glucose monitors, while ketone measurements aligned with blood ketone meters.

Clinical Considerations

• The ring continuously measured glucose, ketones, lactate, uric acid, vitamin C, and alcohol from finger sweat.
• Researchers reported glucose values tracked commercial CGMs and ketone levels tracked established blood-monitoring devices.
• Sweat collection occurred passively through an osmotic hydrogel and did not require exercise-induced perspiration.
• The device remains an investigational prototype requiring broader validation before clinical adoption.

Practice Applications

• Interpret results as early validation of multi-analyte wearable monitoring.
• Recognize growing interest in continuous biochemical monitoring beyond glucose alone.
• Consider potential future applications in diabetes and metabolic-health tracking.
• Monitor larger clinical validation studies and regulatory developments.
