Some of them claim to extrapolate it from sweat, others claim to be
able to estimate it from shining near-infrared at the blood vessels
that are near the surface. Neither method has yet proven to be
accurate, which is why they aren't certified as a medical device in
UK.
You can learn all about it by searching "non-invasive blood glucose
monitoring"
Thanks,
