Huawei has announced a glucose sensor of its own. The Sense G1 is a small round patch worn on the arm that reads sugar levels around the clock, so people with diabetes can look at a number on their phone or Huawei watch instead of pricking a finger.
Huawei’s teaser says it raises an alert when a reading goes abnormal, works for one user only and needs no calibration. A single sensor lasts up to 16 days. Huawei has not put a price or an on-sale date on it.
The more telling detail is regulatory. China’s drug regulator has put the Sense G1 in Class III of its medical-device register, under certificate number 国械注准20263072228, the strictest of the country’s three risk tiers. That tier also covers heart stents and artificial joints, which is why it is a bigger step than a fitness band that estimates health trends. Huawei’s Weibo post introduced the product on 13 November as its first continuous glucose monitoring system.
How it measures is not in Huawei’s teaser. A Chinese tech blogger, who goes by Kan Shan Shu, claims a soft needle under the skin uses glucose oxidase and electrodes to read the fluid between cells, that accuracy (MARD) is below 10%, and that readings trail real blood sugar by 5 to 15 minutes. Huawei has not published any of those figures, so treat them as a tipster’s claims.
Huawei’s poster shows the white disc stuck to the back of an upper arm, with a watch on the wrist showing a reading. It carries the HarmonyOS logo and the line about all-day monitoring, viewing on phone and watch, and abnormal-reading alerts. Whether the sensor works with phones that do not run HarmonyOS is not stated in the teaser.
