A newly printed Samsung patent presents one other take a look at how the corporate is exploring wearable glucose measurement, simply as Samsung individually confirmed that noninvasive steady glucose monitoring stays an lively analysis precedence.
A Samsung European patent software printed Sept. 9 describes a wearable system that mixes biometric indicators with a glucose studying from an exterior machine to create calibration information. That calibration might then assist the wearable decide a person’s glucose values from biometric indicators.
Individually on Sept. 9, Samsung publicly confirmed that it’s nonetheless pursuing noninvasive steady glucose monitoring. Collectively, the developments supply a recent take a look at Samsung’s work on glucose expertise, though the corporate has not introduced a Galaxy Watch able to independently measuring blood glucose.
Samsung patent makes use of an exterior glucose studying for calibration
The Samsung patent, printed as EP4803002A1, describes a wearable digital machine outfitted with sensors, reminiscence, a show, communications {hardware}, and a processor.
Its glucose-measurement course of begins with one thing necessary: a blood glucose studying taken by an exterior machine.
In keeping with the submitting, the wearable can establish a time for the person to measure their glucose utilizing that exterior machine. Across the similar time, a sensor on the wearable collects a biometric sign from the person.
The wearable can then receive the externally measured glucose worth and mix it with the biometric sign to generate calibration information. That calibration information can subsequently be used to find out glucose values from biometric indicators measured by the wearable.
In different phrases, the patent describes a system that might use a recognized glucose measurement to calibrate biometric information collected by a wearable somewhat than anticipating the machine to provide an correct glucose studying from scratch.
The Sept. 9 European publication is new, however the patent household traces its precedence to Dec. 11, 2023. A Korean software was printed June 18, 2025, adopted by a global PCT publication on June 19, 2025.
The submitting additionally refers broadly to a “wearable digital machine.” It doesn’t title a particular Galaxy Watch mannequin or verify that the expertise will likely be included right into a industrial Samsung product.
Samsung says noninvasive glucose analysis remains to be underway
Samsung’s separate feedback on Sept. 9 present well timed context for the patent publication.
Throughout a well being briefing that day, Jong-min Choi, an government vice chairman on Samsung Electronics’ Digital Well being Group, stated Samsung continues to pursue noninvasive steady glucose monitoring by way of a number of approaches.
“We’re pursuing a multifaceted method that features world expertise exploration, in-house analysis, and collaboration with exterior startups (POC),” Choi stated, in line with EDaily. Choi additionally acknowledged the expertise’s challenges, saying Samsung continues to deal with bettering its reliability.
Samsung is trying past the watch alone. Choi stated sporting a Galaxy Ring and Galaxy Watch collectively can considerably enhance sensor measurement accuracy. Samsung’s broader imaginative and prescient entails connecting watches, rings, smartphones, and Galaxy Buds to create a extra personalised AI healthcare ecosystem.
Digital Instances individually reported that Samsung continues to analysis noninvasive glucose monitoring because it expands the Galaxy Watch right into a broader digital-health platform.
The feedback verify that noninvasive steady glucose monitoring stays an lively Samsung analysis effort, not merely expertise described in earlier patent filings.
The patent doesn’t imply a glucose-reading Galaxy Watch is coming
There’s nonetheless a considerable hole between Samsung’s analysis and a Galaxy Watch able to independently measuring blood glucose.
Samsung has not introduced such a Galaxy Watch, offered a launch date for the expertise, or stated that the strategy described in EP4803002A1 will likely be included right into a future product.
TechRepublic has beforehand examined Samsung’s broader blood sugar analysis, together with what present Galaxy Watches can and can’t do. The Sept. 9 patent publication provides a brand new improvement to that longer-running effort somewhat than altering the capabilities of watches already on customers’ wrists.
That distinction is very necessary with glucose expertise.
The U.S. Meals and Drug Administration has warned customers towards smartwatches and good rings that declare to independently measure or estimate blood glucose with out piercing the pores and skin. The company has stated it has not licensed, cleared, or authorized a smartwatch or good ring supposed to independently carry out that operate.
Galaxy Watches already supply well being metrics that may generally create confusion about what the units really measure. Samsung’s AGEs Index, for instance, supplies info on superior glycation finish merchandise however doesn’t present a direct blood glucose studying. TechRepublic has beforehand defined what the Galaxy Watch AGEs Index really measures.

What Galaxy Watch homeowners ought to take from Samsung’s patent
For Galaxy Watch homeowners, nothing modifications as we speak.
The Sept. 9 publication doesn’t add impartial glucose measurement to an present watch, verify the characteristic for Samsung’s subsequent wearable, or set up when the expertise may turn into commercially out there. Anybody who depends on glucose readings for medical selections ought to proceed utilizing appropriately licensed glucose-monitoring expertise.
What has modified is the proof surrounding Samsung’s ongoing work. On Sept. 9, a European patent publication offered an in depth take a look at one method Samsung has explored for calibrating wearable glucose measurements. Individually that day, a Samsung government confirmed that the corporate stays actively excited by fixing the issue of noninvasive steady glucose monitoring.
The following significant indicators will likely be extra concrete: scientific validation outcomes, regulatory filings, or an precise Samsung product announcement.
Till a type of arrives, the patent is greatest considered as a window into Samsung’s analysis somewhat than a preview of the following Galaxy Watch. However for anybody ready for a mainstream smartwatch to make the leap into impartial glucose measurement, Samsung has made one factor clear: it’s nonetheless engaged on the issue.
