Ahhh yes, the second article does have more details and seems more plausible. Much less exciting than the initial headline though of course lol. I will reserve judgment until more information is available but thank you for posting the next link, how innovative this is remains to be seen as similar approaches are already deployed in the field.

Yeah if that’s what Apple has, I don’t consider that a big breakthrough. And micro needles in my smart watch…..hmmm. But I’m willing to keep an open mind. Maybe my standard for “Breakthrough technology” is higher than Business Insider’s which seems highly likely.

I don’t argue with strangers on the interwebs but you are free to look up Beer’s Law or reference any college level physics or chemistry text book. This is not an obscure theory known only by academics. It’s a pretty useful tool that has allowed a lot of current blood analysis equipment to be designed to measure various components quite accurately. Here is an article that summarizes some of the current limitations.

I did not say it’s impossible. I said they’d need to overcome our current understanding of Beer’s Law. And since the article mentioned it is using “optical absorption spectroscopy” this is a relevant assumption. Smart watches only have a basic set of LEDSs, a few photo detectors and possibly some ability to detect changes in electrical impedance….well that’s just not enough to overcome the calibration issue. A lot of people a lot smarter than I am have been working on this question for a long time, so, much like the issue with continuous noninvasive blood pressure, our current tools are not adequate. If they have solved it, great. I look forward to knowing more.

Something called Beer’s Law will prevent this from being true. You need to know the path length to determine the concentration and that has always been why noninvasive continuous glucose monitors fail….unless calibrated and the only way to calibrate is with a finger stick. This has been attempted 1,000 times before. I highly doubt they have found a workaround for this.
