Engineers at the University of California San Diego created a smart ring that simultaneously and continuously monitors up to four different chemical biomarkers from finger sweat. The biomarkers the smart ring can monitor in sweat are glucose, ketones, vitamin C, uric acid, lactate and alcohol.
In a new paper published in Nature Communications, UC San Diego engineers in the lab of Joseph Wang, professor in the Aiiso Yufeng Li Family Department of Chemical and Nano Engineering at the UC San Diego Jacobs School of Engineering, report results from what they believe is the first fully integrated smart ring for daily biochemical monitoring.
“Commercial rings only provide biophysical information, but they lack molecular information about biochemical markers that offers deeper insights about an individual’s health status,” said study first author Tamoghna Saha, a postdoctoral researcher in Wang’s lab.
For the ring to detect biomarkers in sweat, exercise or other exertion is not required; sweat is passively drawn up through the skin’s surface via osmosis using a technique pioneered by Saha.
Tracking multiple biomarkers simultaneously has the potential to broaden the real-time health picture in many scenarios, including diabetes management and nutrition tracking.
