Is there a glucose monitor/sensor that works from the wrist without puncturing the skin?

I've seen patches on the the upper arm that have to be replaced every week or two, sensors that clip on the ear or the skin that stretches between fingers, and things that have to be surgically implanted under the skin, but my understanding is that all of these, even the non-invasive ones, have to be approved by the FDA as medical devices, and come with a pretty substantial legal responsibility.

A blood oxygen sensor helps literally everybody, even the diabetic, while a glucose monitor--assuming it can be made reliable from the wrist--benefits a smaller set. A large set, to be sure, but still a smaller set than "everyone."
