Huawei Sense G1: Company’s First Continuous Glucose Monitor

Huawei has unveiled the Sense G1, the company’s first continuous glucose monitoring device. The arm-worn sensor is designed to track glucose levels day and night and transmit readings to a smartphone or compatible smartwatch.

Design and sensing method

Teaser materials show a small, round sensor that resembles an Apple AirTag and attaches directly to the arm. A tiny needle sits beneath the skin to collect readings from the fluid surrounding cells. The sensor uses glucose oxidase and electrodes to measure glucose in that fluid and convert the results into blood sugar readings, removing the need to prick a finger for each measurement.

Accuracy and regulatory status

A report suggests the Sense G1 has a mean absolute relative difference (MARD) below 10 percent, a metric that compares a CGM’s readings to laboratory reference measurements. A tipster also claims glucose readings can lag behind actual blood sugar levels by around 5 to 15 minutes. China’s National Medical Products Administration approved the Huawei Sense G1 as a Class III medical device.

Class III is the country’s highest medical device risk category and covers products such as cardiac stents and artificial joints. The Sense G1 is the first Class III medical device from Huawei’s consumer hardware business.

Usage, development and availability

Huawei has shared several everyday-use details about the Sense G1. The company describes the sensor as intended for a single user, requiring no calibration, with a sensor lifespan of up to 16 days.

• Single-user device
• No calibration required
• Sensor lifespan up to 16 days

Li Xiaolong, CTO of Huawei Terminal BG, said the Sense G1 "has been the longest development project the company has undertaken." He first wore a test version in December 2023, a timeline Huawei says results in roughly 35 months of testing and development.

Huawei has been expanding its health monitoring work: the company introduced its TruSense health monitoring system in 2024, and its smartwatches can assess diabetes risk but cannot directly measure glucose levels. The Sense G1 is intended to provide direct glucose measurement where watches cannot.

Huawei has not announced pricing or a sale date. The company could disclose more details at an event later this month, where it may also introduce the Huawei Mate X8 foldable and the MateBook Fold S, the latter expected to follow the original MateBook Fold Ultimate Design.
