Glucose monitoring on Apple watch

This is definitely a plant.

Here’s straight from the press-release portal (not a news source), Bloomberg.

Apple Watch Blood Glucose Monitor Could Revolutionize Diabetes Care (AAPL) – Bloomberg

Apple is taking a different approach, using a chip technology known as silicon photonics and a measurement process called optical absorption spectroscopy. The system uses lasers to emit specific wavelengths of light into an area below the skin where there is interstitial fluid — substances that leak out of capillaries — that can be absorbed by glucose. The light is then reflected back to the sensor in a way that indicates the concentration of glucose. An algorithm then determines a person’s blood glucose level.

I haven’t seen any other source, and this popped up on TechMeme. I thought of linking it here, because this is something which isn’t “new”, but non-invasive monitoring has been on the “radar” for a long time.

Here’s a very quick search on Google:

Non-Invasive Blood Glucose Monitoring Technology: A Review – PMC

Over the past 60 years, after three leaps and bounds, the intrinsic principles of electrochemical glucose sensors have been enriched and their outward performance has been greatly improved. Numerous technological innovations (including material, structural, and electrochemical analysis) have opened the door to a wide range of electrochemical glucose biosensors, making glucose sensors highly successful not only in invasive systems, but also in an increasing number of applications in non-invasive monitoring systems.

Here’s from the same write up:

This is just an example.

I am keen to understand how they will get the regulatory approvals. Apple seriously has a foothold in the healthcare (or “wellness” market). It’s expanding in front of our eyes!
