Huawei has entered the continuous glucose monitoring market with the Sense G1, a circular sensor worn on the upper arm that tracks glucose throughout the day. Readings can be viewed on a connected phone or smartwatch, while the system can send alerts when it detects abnormal values.
The watch does not perform the measurement itself. Presentation images show it displaying a glucose trend graph, while the arm-mounted sensor handles the readings. Huawei Consumer Business head He Gang had previously indicated in September that the company was developing such a product.
Information published by Chinese media describes a flexible filament placed beneath the skin, alongside a glucose oxidase and electrode system. Like other CGM products, the sensor measures glucose in interstitial fluid—the fluid between cells—rather than directly in blood. That approach enables ongoing trend monitoring between individual finger-prick glucose meter tests.
Pre-announcement details pointed to a mean absolute relative difference (MARD) below 10%, a roughly 5- to 15-minute delay relative to changes in blood glucose, and a wear period of about two weeks. Those reports also said the device could be used while swimming. The delay is associated with the time it takes for glucose changes in the bloodstream to be reflected in interstitial fluid.
Sense G1 creates a new connected-device category for Huawei's phone and smartwatch ecosystem. Pricing, launch markets, regulatory status, and the full list of compatible devices have not been detailed in the available announcement information.
