SiBionics unveiled its GS3 continuous glucose monitor (CGM), which now has CE mark approval. The company unveiled the device — which it touts as the world’s thinnest CGM — at last week’s 18th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD) in Amsterdam.

GS3 features an ultra-compact design and three-second activation. With a thickness of just 2.9 mm, China-based SiBionics compares its size to that of a small coin. It also weighs just 1.5 grams, which the company says makes it “almost unnoticeable when worn.”

The CGM features three connection methods for compatibility with a variety of smartphones. Its NFC-enabled three-second connection capability allows for instant pairing with a simple tap. SiBionics also integrated multiple AI capabilities to help better understand glucose data and enable effective self-management.

Users can also connect their GS3 directly with their smartwatch and a receiver for the personalized needs of a wide range of users. Continuous algorithm enhancements further improve monitoring stability and accuracy as well.

“With the launch of GS3, SiBionics continues to lead CGM innovation, aiming to provide a lighter, more precise, and smarter glucose monitoring experience for people with diabetes worldwide,” the company said in a news release.

SiBionics brings the GS3 CGM to the market at an interesting time as it remains embroiled in a patent battle with leading CGM maker Abbott. Last summer, The Hague said the company can’t distribute its CGMs in Germany, France, the Netherlands and Ireland.
