Non-invasive Blood Glucose Monitoring is a technology that hasn’t quite matured yet. However, a report by ETNews says that Apple and Samsung might finally be able to implement “Blood sugar monitoring” on their next smartwatches.

The report says that both Samsung and Apple will introduce the non-conventional method of Blood Sugar monitoring on their Galaxy Watch 4/Watch Active 3 and Watch 7* respectively. That is, the glucometer inside the smartwatches will apparently be based on an optical sensor.

This is not the first time we are hearing about this. A couple of weeks ago, we saw a company called Quantum Operation showing off a “Spectrometer-based” prototype that works on the interaction of light with the wrist. We already know that companies like Apple have been actively working on it for more than a year now.

And to affirm this, the report says that both of them have secured their patents and are now working on increasing the reliability. Apple’s patent dates back to 2018 whereas Samsung collaborated with MIT to post results of Raman’s Spectroscopy on journal “Science Advances”.

For the unware, it is how a Light interacts with chemical bonds of a material. When you irradiate laser light onto a substance, it scatters. These differing wavelengths can be used to monitor the Blood Glucose accurately than before. If the report is true, Diabetic patients can finally be free of having to constantly prick their fingers with needles.

Samsung and Apple are the right companies to popularise this as others despite advancing aren’t really progressing beyond prototypes. That said, both the companies will reportedly introduce this as early as this year. Out of this, Samsung is planning three new watches in H2 2021 and one/two might get this feature.

With Smartwatches pressing the saddle in 2021, I think this is the right time to introduce a game-changing feature on wearables.

*- Smartwatches’ Names are Tentative.
