The wearables industry has made great strides. We have gadgets for step counting, sleep tracking, and even spotting heart issues. But one big challenge remains: non-invasive blood sugar monitoring. For many, especially diabetics, keeping track of blood sugar without painful pricks is essential.
Diabetics must constantly monitor their blood sugar to avoid serious health issues. This task is particularly burdensome for young children and the elderly, as usual methods involve needle pricks or continuous glucose monitors (CGMs) that require insertion under the skin.
Interestingly, CGMs are gaining popularity among non-diabetics too, especially as weight-loss methods become trendy. Following a diabetic-friendly diet—rich in protein and fiber while low in sugar—has caught on for those wanting to shed pounds. Companies like Apple have been trying for years to add a no-prick glucose monitor to their products, but so far, it hasn’t materialized.
Recently at CES 2026 in Las Vegas, I came across an exciting new device called the PreEvnt Isaac. It’s tiny—about the size of a quarter—and monitors your blood sugar through your breath instead of your skin. It looks for volatile organic compounds like acetone, which can signal rising blood sugar levels. This means no more bathroom trips for a painful prick! You can keep the Isaac around your neck or in your bag, making life a little easier for many.
The Isaac is named after the inventor’s grandson, who was diagnosed with type 1 diabetes at a young age. Bud Wilcox, the inventor, realized that the sweet, fruity breath typical in diabetics could be a game-changer for monitoring blood sugar.
This innovative concept was first shown at CES 2025 and later began human clinical trials at Indiana University. These trials are comparing the Isaac’s performance with traditional blood sugar monitoring methods, starting with teenagers with type 1 diabetes and expanding to adults with type 2.
The results will be crucial, as the device is eyeing FDA review in the coming year. If successful, the Isaac could significantly improve quality of life for many people who struggle with constant monitoring.
