Following on from a recent post https://forum.diabetes.org.uk/board...sive-watch-that-monitors-blood-glucose.90783/ about a glucose monitor watch, it seems the big guns have beat them to it! and this could be a massive money spinner for Samsung.

Samsung has been working on non-invasive techniques for blood glucose monitoring for a while now. Last year, it developed a method for monitoring blood glucose levels using a method called Raman spectroscopy. The process uses lasers to identify chemical composition, and according to Samsung, it demonstrates the “highest prediction accuracies among non-invasive technologies.”

The new ability could make it much easier for people with diabetes to track their daily blood sugar levels. The tech reportedly uses an optical sensor to determine the readings, eliminating the need for drawing blood. It’s similar to how a number of smartwatches, including the Galaxy Watch 3, provide blood oxygen or SpO2 readings.

Samsung's next smartwatch could bring diabetes monitoring to your wrist

A new report says Samsung will include an optical sensor for diabetes monitoring on its next Galaxy Watch launching later this year.

Apple Watch Series 7 Rumored to Feature Blood Glucose Monitoring

The Apple Watch Series 7 will reportedly feature blood glucose monitoring via an optical sensor, according to ETNews. The report, which mainly...

This is the MIT/Samsung paper referred to, just published: https://advances.sciencemag.org/content/6/4/eaay5206

Interesting, but it really looks to me like something still at proof of concept stage & a long way to go before there's a product.

To bring the Raman-based blood glucose monitoring technology to people with diabetes, challenges still remain for further developments: for example, lowering the maximum glucose concentration in experiments, reducing the integration time, miniaturizing the system, and testing with many human subjects, including people with diabetes and with different skin colors. Improving the Raman system and developing sophisticated prediction algorithms will be our future work, and the work we presented here will be a solid basis for further improvements.

Suggestions that it'll be launched later this year look like the usual FUD PR move to me (ie muddying the waters for competitors looking for funding etc etc).
 
if it did happen then you could use a normal meter to compare how accurate the thing is.
 
Rather agree with Eddy, a lot of things to sort out before it becomes a "watch" as opposed to something you pull behind you on a trolly.

Hi DocB,

Would nano technology make this feasible? The way they promote this, is if it will be available on its next release.
Interesting timing, considering my other post about a start up company making the news....is it just to scare off competitors?
 
My daughter, who has asthma, has an oximeter for home use, more or less the same as those used in hospital, except it has a display to show the reading. Came in handy when she had Covid recently. That is not something you drag behind in a trolley, DocB,😉

So there a two problems with this idea. The main one, of course, is the accuracy of BG measurement. The second one is screamingly obvious - battery life. My Apple watch struggles to crack 24 hours before a charge is needed, and the best it can do medically is a basic ECG. So I don't think Abbott will be breaking into a sweat. I fear this will end up as an entertaining back up to our standard systems only available to the gullible rich.

Or (about as likely) it never actually appears. (It's not the first year it's been rumoured as an Apple product, and likely it's been rumoured for Samsung before.)
 
@mikeyB, measuring the amount of light passing through your finger is a bit different to using Raman Spectography to assay blood for glucose. Even if you can miniaturise the kit - a reasonable powerful laser and a spectrometer and the power supplies for both - you are still going to need a lot of computing power to sort out signals from noise. Not saying it can't happen but there are quite a lot of tricky problems to solve before anybody gets there.

Batt life is a top 5 bread'n'butter question for any product like this. I doubt they are anywhere close to really thinking about it.
 
Just occurred to me. A consequence of making glucose monitoring widely available would lead to many more self diagnosis of all types of diabetes.

Imagine that, you buy a new watch and find out you are diabetic!
