Huawei’s New Arm Sensor Can Track Glucose for Up to 16 Days

Huawei has introduced the Sense G1, its first continuous glucose monitor (CGM) in China. The sensor sticks to the upper arm and monitors glucose levels for up to 16 days without needing to prick the finger. Users can receive alerts when readings deviate from the target range and can check their glucose levels on a compatible device.

The compact, spherical sensor is reminiscent of an Apple AirTag. It employs a flexible probe beneath the skin, an enzyme referred to as glucose oxidase, and electrodes to gauge glucose levels in the fluid surrounding cells. This enables users to receive a constant record of glucose fluctuations without the need for individual readings.

Huawei claims each sensor is intended for a single individual and does not require any manual calibration. The Sense G1's accuracy has been confirmed by a source cited by Mydrivers, which reported a mean absolute relative difference (MARD) under 10%. MARD quantifies how closely a sensor's readings align with reference measurements, with a lower number indicating greater similarity.

Additionally, the tipster indicated that readings may lag behind changes in blood glucose by approximately 5 to 15 minutes, although Huawei has not verified these figures. China's National Medical Products Administration granted the Sense G1 Class III registration, the highest risk category for medical devices in China. This marks the first Class III registration for Huawei's consumer hardware division.

Huawei's CTO, Li Xiaolong, disclosed that the Sense G1 had the most extended development period among any product his team has worked on, with the first test unit worn in December 2023, approximately 35 months prior to its unveiling. Huawei unveiled its TruSense health monitoring system in 2024. Certain smartwatches within the system can evaluate diabetes risk, while the Sense G1 supplies continuous glucose readings via a dedicated arm sensor.

Huawei has not disclosed the price or release date for the Sense G1. The company may provide additional details at a late-November event, where it may also introduce the Mate X8 foldable phone and the MateBook Fold S, a successor to the MateBook Fold Ultimate Design.
