News Summary

• Engineers at the University of California at San Diego have developed a smart ring that, using osmosis, continuously measures the biomarkers of alcohol, glucose, ketone, lactate, Vitamin C (ascorbic acid), and uric acid.
• Through Saha’s painless, osmotic hydrogel perspiration-sampling method, the ring doesn’t require users to exercise enough to start sweating.
• In trials, the UC San Diego smart ring performed well compared with the type of continuous glucose monitors (CGMs) that people with type-1 diabetes use.
