i'm not a smartwatch fan for the most part but i'd get one for CGM use if it meant no more knocking my sensors off walking through doors (because i'm apparently incapable of walking without moving like a wacky inflatable tube man) or nasty adhesive residue stuck on my arms.
To be clear, the research has been going on for a while.
But extracting an accurate enough signal from noise through the skin is an incredibly complex signal analysis problem. And there are multiple approaches.
Nothing has FDA approval yet because it's a major question whether any technology developed thus far is accurate enough. I understand there's at least one clinical trial going on right now. Fingers crossed...
This is pretty much the holy grail, that would make the first person to crack it crazy rich.
So the quick answer is: no, not even close. Also, you would somehow have to measure a very low concentration of soluble chemical in a fluid with always changing composition of a bunch of chemically similar other constituents across relatively wide tissue layers that themselves have a lot of that same chemical..
They're all on a subscription model, you're spending who-knows-how-much per year on a new sensor every few days/weeks. Afraid it'd feel like a prickleburr stuck to me constantly.

Which - to be clear - is because the sensor chemically degrades over time. It's not just rent-seeking; they genuinely don't know how to make one that'll last longer.
I'm the ADD type that runs into shit, or at least I clip corners regularly when going through doorways. Normally... I don't even notice. Ripped two CGM's out in the first month. Shit HURTS.
