The wearables business has solved the comparatively simple stuff: step counting, sleep monitoring, health teaching. It has additionally solved extra complicated issues like detecting atrial fibrillation and sleep apnea. Whereas all of those biometrics are helpful, the continual monitoring of blood sugar in a method that’s noninvasive (that means it doesn’t contain needles) has eluded the makers of fitness tracking units.
Diabetics want to observe their blood sugar continually to verify it doesn’t go too excessive and harm their organs. That is particularly arduous for aged folks and young children, since monitoring blood sugar often requires a pinprick blood take a look at or a steady glucose monitor (CGM), which additionally reaches below the pores and skin.
CGMs have additionally develop into vastly well-liked amongst non-diabetics because the popularity of GLP-1s has skyrocketed. Eating like a diabetic—a lot of protein and fiber, minimal sugar and carbs—is an effective way to shed extra pounds. Apple, amongst different firms, has spent years, and millions of dollars, attempting to introduce a no-prick blood glucose monitor to the Apple Watch, however the characteristic hasn’t arrived but.
All that is to elucidate why I may scarcely imagine that the PreEvnt Isaac was actual once I noticed it right here at CES 2026 in Las Vegas. The Isaac is a small system, concerning the dimension of 1 / 4. As a substitute of monitoring blood glucose optically via the pores and skin, it measures risky natural compounds in your breath to detect biomarkers like acetone that may be correlated with rising blood glucose ranges.
You won’t be capable of put on it in a sensible ring or watch, however a small system that you may put on round your neck or hold in your bag with out having to retreat to the toilet to prick your pores and skin is a big step up in high quality of life for a lot of, many individuals.
Upcoming FDA Authorization

The Isaac is known as after the inventor’s grandson, who was recognized with kind 1 diabetes at 2 years previous. A 2-year-old doesn’t need to get pricked continually. Bud Wilcox realized that “acetone breath”—that candy, fruity breath that may be a frequent diabetic symptom—might be used to verify for blood sugar occasions.
PreEvnt and Wilcox showcased the idea at CES 2025 (it didn’t appear actual then, both). Later that yr, the system entered energetic human medical trials at Indiana College. The research is evaluating Isaac’s efficiency with monitoring blood sugar ranges as in comparison with conventional blood sugar monitoring, beginning with adolescents with kind 1 diabetes after which increasing to adults with kind 2 diabetes.
The trials are being carried out with an eye fixed towards regulatory evaluation by the US Meals and Drug Administration within the upcoming yr.
