A prototype smart ring developed by engineers at the University of California appears to have cracked one of the holy grails of health wearables: non-invasive blood sugar measurement. The data is sent to a companion app on a paired iPhone.
While existing smart rings rely purely on biophysical data extracted from sensors like those embedded into the Apple Watch, this ring also tracks chemical biomarkers by analysing sweat …
Today’s smart rings work in exactly the same way as the Apple Watch, using exactly the same sensors. These enable the collection of an impressive range of data, including resting heart rate, heart rate variability, respiratory rate, temperature, cardiovascular age, activity, sleep cycles, and more.
But supplementing existing sensors with molecular ones could dramatically increase the amount of health data that can be gathered. You don’t even have to work up a sweat, as CNET reports that the technology is able to pull sweat from your skin.
