Huawei Unveils Sense G1 Continuous Glucose Monitor With 16-Day Wear Time

Huawei has introduced the Sense G1, its first continuous glucose monitor, in China. The small, round sensor is worn on the upper arm and tracks glucose levels around the clock for up to 16 days, sending alerts when readings move outside a user's target range. Readings can be viewed on a compatible phone or smartwatch, according to the company.

The device resembles the shape of an Apple AirTag. Reports indicate it uses a flexible probe placed beneath the skin along with the enzyme glucose oxidase and electrodes to measure glucose in the fluid surrounding cells. This approach gives users a continuous record of glucose changes without a finger prick for every reading. Huawei says each sensor is intended for a single user and requires no manual calibration.

A tipster cited in media reports put the Sense G1's mean absolute relative difference below 10 percent, a measure of how closely a sensor's readings match reference measurements, where a lower figure indicates closer agreement. The same tipster said readings could lag behind blood glucose changes by roughly five to 15 minutes. Huawei has not confirmed either figure.

China's National Medical Products Administration registered the Sense G1 as a Class III medical device, the country's highest risk category, which also covers products such as cardiac stents and artificial joints. According to IT Home, this is the first Class III registration for Huawei's consumer hardware business.

Huawei consumer business CTO Li Xiaolong said the Sense G1 had the longest development cycle of any product his team has worked on, noting that he first wore a test unit in December 2023. Huawei introduced its TruSense health monitoring system in 2024; some of its smartwatches can assess diabetes risk, while the Sense G1 delivers continuous glucose readings through a dedicated arm sensor.

Huawei has not yet announced a price or sale date. The company could share more details at a late-November event, where it may also introduce the Mate X8 foldable phone and the MateBook Fold S.
