Huawei has launched the world's first smart watch that can non-invasively measure blood sugar levels. The Huawei Watch 4 doesn't display the exact sugar level, but it can alert you when it's high.
As reported by Huawei Central, the smart watch makes a conclusion about the glucose level based on the heart rate and electrocardiogram data of the last week, which means that the user has to wear the watch for the recent seven days.
The new watch also has support for eSIM, GPS and Always-on Display mode. It runs on HarmonyOS 3.0 operating system.
The Huawei Watch 4 series consists of two models: base and Pro. Both devices have a 1.5-inch screen (with a resolution of 466 x 466 pixels), are water-resistant to a depth of 50 meters. They differ in materials used in the body, sizes and battery capacity: for some reason the battery capacities are not listed, but the Huawei Watch 4 is reported to last up to three days on a single charge, and the Huawei Watch 4 Pro up to four or even five days.
The Huawei Watch 4 starts at 2,700 yuan (about $380), while the Pro model starts at 3,400 yuan (about $480).
Apple is also developing a technology to measure the level of sugar in the blood with a non-invasive method. Although the company has tested the technology on hundreds of people over the past 10 years, it is still in the proof-of-concept stage. However, the company has already made some progress and intends to use it in the Apple Watch.
