Apple Watch Series 7, Samsung Galaxy Watch 4, and Samsung Galaxy Watch Active 3 could all feature a non-invasive glucose monitor

It has been estimated that over 460 million people around the world have diabetes, and it is very important to keep an eye on blood sugar levels when diagnosed with this debilitating disorder. It appears both Apple and Samsung want to produce smartwatches that incorporate a non-invasive method of measuring blood glucose levels. According to the Korean media site ETNews (via GadgetsandWearables), such a crucial glucose monitor could find its way into the Apple Watch Series 7 or the Samsung Galaxy Watch 4/Galaxy Watch Active 3.

A non-invasive method of testing blood sugar levels without drawing blood would certainly appeal to many and would be a valuable selling point for any future smartwatch from either Apple or Samsung. A Japanese company called Quantum Operations Inc has already come up with this type of glucose monitor housed in a wearable, which utilizes spectrum sensor technology that allows the device to constantly monitor the user’s glucose level without the requirement for a needle. It has been speculated that Apple and Samsung will use similar technology for continuous glucose monitoring on the Apple Watch 7 and Galaxy Watch 4/Active 3, respectively.

If either the Apple Watch Series 7 or Samsung Galaxy Watch 4 comes with an accurate glucose monitor alongside the health-related tools many smartwatches usually offer, such as heart-rate tracker and SpO2 measurement, then they will likely appeal to millions of people worldwide who have to deal with the effects and management of diabetes. Samsung has been working in collaboration with the Massachusetts Institute of Technology specifically with Raman spectroscopy, which studies the vibration patterns of molecules to provide the required data.
