Infrared. Got it. Thanks.

  It is called near-infrared spectroscopy ("NIRS") and you can read more about it here: https://en.wikipedia.org/wiki/Near-infrared_spectroscopy https://en.wikipedia.org/wiki/Near-infrared_spectroscopy

  Could be something else. The wikipedia page on this technology (https://en.wikipedia.org/wiki/Noninvasive_glucose_monitor https://en.wikipedia.org/wiki/Noninvasive_glucose_monitor) mentions “bioimpedance spectroscopy, microwave/RF sensing, fluorescence technology, mid-infrared spectroscopy, near infrared spectroscopy, optical coherence tomography, optical polarimetry, raman spectroscopy, reverse iontophoresis, and ultrasound technolog“ That page also claims there isn’t any clinically or commercially viable product yet. That seems out of date to me, given that https://www.labiotech.eu/best-biotech/needle-free-glucose-monitoring-for-diabetes-medtech/ https://www.labiotech.eu/best-biotech/needle-free-glucose-mo... mentions 8 devices you can buy now.

"needle free" !- "non-invasive". Several of those devices are implanted subdermally.

    > raman spectroscopy And now I can’t stop thinking about wearing a Raman spectrometer on my wrist :)
