Samsung may pick off the Galaxy Watch 3 with three smartwatch models. Rumours say that they will be officially released at the next Galaxy Unpacked Event. One of the three models will be mostly health-related and have the latest health technology in the bundle.

The smartwatch will be equipped with a sensor that may be able to read people's glucose levels. This may be extremely useful for people diagnosed with diabetes. Our sources haven't made up their minds on the name of these smartwatches, but we can guess that it may come out as the Galaxy Watch 4 or the Galaxy Watch Active 3, but the other models.

The Galaxy Watch sensor may utilise Raman spectroscopy

Industry sources haven’t been able to reveal the exact technical details of Samsung’s upcoming smartwatch but judging by past events, the Galaxy Watch 4 / Galaxy Watch Active 3’s blood glucose sensor might utilize a technique known as Raman spectroscopy.

It was exactly one year ago when Samsung Electronics together with the Samsung Advanced Institute of Technology (SAIT) and the Massachusetts Institute of Technology (MIT) have revealed a non-invasive method of monitoring glucose levels that utilizes Raman spectroscopy.

In Layman’s terms, a sensor based on Raman spectroscopy utilizes lasers to identify chemical compositions. In practice, this technology should allow for accurate blood glucose level readings without having to prick the patient’s fingertip.

It’s only the beginning of 2021 and we’re many months away from the next Unpacked event, which means there’s a lot of time left for leaks and rumours. But as far as the new blood glucose level sensor is concerned, it might be required to go through lengthier approval processes — same as ECG —  so only time will tell if it will reach the consumer market this year.
