INTERNATIONAL DESK — Huawei has unveiled the Sense G1, its first continuous glucose monitor (CGM), in China. The sensor attaches to the upper arm and tracks glucose day and night for up to 16 days.
It can send alerts when readings go outside the target range, and users can check their glucose levels on a compatible phone or smartwatch. How It Works The small, round sensor resembles an Apple AirTag. According to Mydrivers, it uses a flexible probe beneath the skin, an enzyme called glucose oxidase, and electrodes to measure glucose in the fluid around cells.
This gives users a continuous record of glucose changes without a finger prick for each reading. Huawei says each sensor is for one person and requires no manual calibration. A tipster cited by Mydrivers put the Sense G1’s mean absolute relative difference (MARD) below 10%.
MARD measures how closely a sensor’s readings match reference measurements. A lower figure means closer agreement. The tipster also said readings could lag behind changes in blood glucose by about 5 to 15 minutes.
