A report from a Korean outlet News AND suggests that Apple and Samsung are both making efforts to achieve blood sugar monitoring in their upcoming smartwatch models. The report focuses primarily on Samsung, which is expected to announce three wearable devices at the company’s second Unpacked event of the year. In the second half of 2021, Samsung’s wearable devices could be announced alongside its new line of foldable phones. The blood level function would come either to the “Galaxy Watch 4” or to the “Galaxy Watch Active3”. Both are tentative names as Samsung has yet to confirm the name of its next watches.
The feature uses an optical sensor capable of detecting levels of blood glucose (sugar), which is vital for people with diabetes. This normally involves drawing blood and using a device that detects the amount of glucose in the blood sample.

This method that Samsung plans to use is based on Raman spectroscopy and was developed by research conducted by Samsung and MIT. The optical sensor collects information from wavelengths caused by vibrations of a material when laser light is scattered after hitting the material. The accuracy of this signal is what MIT and Samsung were able to achieve.
Apple and Samsung were successful in introducing ECG capabilities in both the Apple Watch Series 6 and the Samsung Galaxy Watch 3. Of course, these two companies had to face government approval before the features could be put in place. because they are medical grade technologies. We expect these companies to face the same type of government approval process if and when blood sugar monitoring gets to mainstream smartwatches.
