The world of continuous glucose monitoring (CGM) is evolving faster than ever. In recent years, we’ve seen sensors become smaller, more accurate, and more connected — but the next generation of CGMs goes far beyond that. A new wave of companies is reimagining how glucose is measured altogether, trading adhesive patches and needles for implantables, optical sensors, and even devices that read electrical signals from the brain.

Among the most ambitious innovations are implantable sensors designed to measure glucose directly from the bloodstream. Glucotrack’s “continuous blood glucose monitor” (CBGM) could last up to three years under the skin and deliver real-time data without the 10-minute lag common in interstitial readings. Meanwhile, Eversense is developing its next-generation implantable sensors, including a fully internal Bluetooth-enabled model that would eliminate the need for an external transmitter.

But it’s not just about implants. Companies like Biolinq, Sava, and Trinity Biotech are pioneering needle-free sensors that sit closer to the skin’s surface and can detect multiple analytes beyond glucose, including ketones, lactate, and stress hormones. And in a bold new direction, SynchNeuro is developing a wearable that uses EEG brainwave signals to monitor glucose in real time, potentially offering the world’s first truly non-invasive CGM. Even Apple and Samsung are continuing their long-rumored work on laser-based glucose tracking for future wearables.

For a deeper dive into these groundbreaking technologies — from implantables and brainwave sensors to breath-based and multi-analyte CGMs — watch our full roundup with all the details in our Next-Gen CGMs video at the top of this page.
