Earlier this month, tech sites spotted a patent for an ambitious Fitbit smart ring, built to track blood pressure, glucose, lipids, hemoglobin, and your diet, plus the usual essentials. I don't know if a Fitbit or Pixel Ring could pull these off, but it doesn't matter. It's just one of many future smart rings that'll succeed (or fail) based on the name on the box.
Gadgets & Wearables first spotted the U.S. patent from Fitbit, titled "Ring for optically measuring biometric data." According to the filing, Fitbit first applied for a smart ring patent in 2019, refiled this application in 2020, and finally had it accepted this June.
