I'm actually part of a research team working on using a wrist mounted spectrometer to actually measure glucose continuously and non-invasively. Turns out it's a really really hard problem.

If you crack it is there anything preventing using the same tech to get a whole host of measurements like vitamin levels or other blood components? I'm imagining you are going down the same path as oxygen saturation meters except it's way easier measuring elemental content than complex molecules. What's the hardest problem, if I may ask?

[rusticpenn]

It can measure the differences in spikes pretty well I think. The problem is with absolute values. ( was experimenting on myself)

Oh exciting! That’s a billion dollar invention if you crack it.

Do you mind sharing who the team is? Do they have any literature available?

Rockley Photonics is working on this:

There was a press release last year because they're an Apple partner. I have high hopes but I keep remembering that Theranos had a lot of promise too.

All I keep hearing is that Apple is pouring a fortune into cracking this problem. They've certainly been snapping up every prominent person in the industry in the last decade.

Nice. T1 here wishing you success!
