I just read the accepted patent application from MOVANO where it specifically states RF technology for the measurement of blood glucose, blood pressure and heart rate in claims 24-27. One more step…still need the FDA on board for the glucose part.
But not relevant to anything that’s actually happening now. The Evie ring did not apply for glucose. They did for blood oxygen though. The Apple Watch is violating blood oxygen patents. Glucose is pie in the sky. I think we can all agree we don’t want our smart rings and watches drinking our blood throughout the day to measure glucose levels. At best glucose is what, a decade away, if it ever reliably happens in a watch or ring. Without drinking our blood.
