A smartwatch that tracks blood sugar with out needles continues to be a 2026 tech dream. But because of AI, it’s now nearer than you suppose.
The story beneath it has modified: essentially the most consequential advances in glucose monitoring are now not taking place in sensor labs alone. They’re taking place in software program, the place AI is popping a flood of glucose information into one thing nearer to a private metabolic advisor.
For IT leaders, healthcare enterprise managers, and digital well being builders, the speedy future isn’t a few watch that measures blood sugar. It’s about constructing an clever information ecosystem that may securely combination, translate, and act on metabolic telemetry.
The wrist nonetheless is not a lab
In February 2024, the FDA issued a security communication telling shoppers to not belief any smartwatch or sensible ring that claims to measure blood glucose with out piercing the pores and skin. The company studies that it had recognized dozens of corporations advertising and marketing such units beneath a number of model names and warned that incorrect readings could lead on somebody to take the unsuitable dose of insulin or different remedy.
Some of the results of utilizing the mentioned units vary from confusion to coma. That warning stays in drive right this moment, and no smartwatch or ring has since gained an FDA clearance to measure glucose noninvasively by itself.
Crucially, the warning carves out an exception: watch apps that merely show information from an FDA-authorized steady glucose monitor, or CGM. That distinction is the hinge all the trade is now constructed round.
Apple’s decade-long mission simply modified fingers
Apple’s noninvasive glucose sensor, reportedly conceived throughout the Steve Jobs period, continues to be in improvement greater than 15 years later. What modified this spring is who’s working it.
Bloomberg’s Mark Gurman reported in May that Apple shifted oversight of the mission from platform structure chief Tim Millet to Zongjian Chen, the engineering chief who additionally oversees Apple’s Advanced Technologies Group and modem {hardware}. Gurman described the handoff as a sign that Apple believes the science might lastly be far sufficient alongside to maneuver towards a shippable product, although no timeline has been given.
Elsewhere within the noninvasive area, a CES 2026 showcase system known as the PreEvnt Isaac took a unique method completely. It detects acetone within the breath, a biomarker related to rising glucose, quite than sensing by way of the pores and skin. It’s not precisely a watch however a pendant-style system that’s nonetheless beneath scientific trials. This system illustrates what number of parallel paths towards noninvasive detection are nonetheless being examined.
Samsung is constructing the AI layer as an alternative of ready on the sensor
Samsung has taken a extra incremental route. Current Galaxy Watch fashions cannot measure glucose straight, however the firm has spent years laying analytical groundwork round it.
The Galaxy Watcheight collection launched an Antioxidant Index, which makes use of light-based spectroscopy on a fingertip to estimate carotenoid ranges tied to fruit and vegetable consumption, plus an AGEs Index that runs in a single day to trace a marker linked to how shortly the physique accumulates age-related metabolic byproducts. Samsung has described the underlying sensor work as an eight-year R&D effort that included scientific validation towards blood carotenoid ranges and Raman spectroscopy.
Samsung executives additionally confirmed lively analysis into an optical, noninvasive glucose sensor, although no launch date was offered. In the meantime, Galaxy Watch serves as a show and alert floor for suitable CGMs from Dexcom and others, layered with Samsung’s personal metabolic well being metrics.
The actual product delivery right this moment: AI-coached, prescription-free CGMs
The most mature a part of this ecosystem is not a watch in any respect. It’s the emergence of over-the-counter steady…
