Huawei has unveiled its first continuous glucose monitor—the Sense G1, which works with Huawei phones, smartwatches, and fitness bands. This gadget could change the game for people with diabetes and give them an easy way to keep an eye on their blood sugar levels.

The company announced the new health-oriented wearable in a post on the Chinese social network Weibo. There's no information on specific features or pricing, but there have been some leaks and certification documents in the past couple of weeks hinting at what this gadget can do.

The smart monitor uses a soft needle, a glucose oxidase process, and electrodes to measure glucose continuously. The interesting part is that the measurement is non-invasive (sort of), because it measures the values in interstitial fluid rather than in the blood. Smart algorithms then convert these readings into blood glucose values.
The Sense G1 is a serious medical tool
According to local news outlet ITHome, the Huawei Sense G1 received Class III certification from the National Medical Products Administration on October 30.
Class III medical devices are the highest tier in China's medical regulatory system, including heart stents and artificial joints.

Huawei registered its Watch D blood pressure monitoring smartwatches under Class II certification, making this new glucose monitor the company's most serious gadget from a medical perspective, competing with clinical-grade monitors.
The regulatory documents shed some light on some of the features of the Sense G1. The MARD value (Mean Absolute Relative Difference) is less than 10%. This metric measures the accuracy of blood glucose monitors, and a value under 10% places it among popular devices on the market (MARD values ranging from 8% to 10.2%).
The data delay is believed to be between 5 and 15 minutes. The Sense G1 also has a built-in system that alerts the user to sudden spikes or falls in readings. According to ITHome, you can swim with the Sense G1, and it can be worn for up to two weeks.
Sense G1 has been a long time in the making

Another interesting tidbit of information comes from one of the comments under the official Huawei post on Weibo.
One of the users, going by the nickname Brice Lee, posted that he was part of the development of the Sense G1 and that he was wearing the product back in 2023. According to Mr. Lee, his friends wore the monitor as part of beta testing even earlier than that.
The reason for the delay might be Huawei acquiring the necessary certification for the device. Is this a game changer?
Huawei is serious about health tracking, but there's a catch

The company recently launched the latest iteration of its blood pressure monitoring smartwatch, the Huawei Watch D3. I took it for a spin and found it quite accurate, as well as comfortable and stylish. You can check out our detailed review for a deep dive.
Now, the Sense G1 has been certified in China, but the chance of it coming to the global market and the US is pretty slim, at least for now. The gadget is dependent on the Huawei ecosystem and uses HarmonyOS, so a global launch won't be straightforward.
There are other blood glucose monitors on the market, especially in the US, such as the Dexcom G7, and most of them work with both iPhone and Android devices.
What's interesting is that Huawei is dipping its toes into medical-grade devices, and that is something Apple and Samsung might want to pay attention to.
