Huawei Watch 4 Series: The World's First Non-Invasive Blood Sugar Tracker

Huawei Watch 4 claims to have a new suite of features dedicated to assessing high blood sugar in those with diabetes or pre-diabetes, including a hyperglycemic risk assessment to detect abnormal blood sugar levels. However, it's not clear how the smartwatch collects blood sugar data without drawing blood. The rest of the Huawei Watch 4 specs include HarmonyOS 3.1, a 1.5-inch AMOLED display, and almost 5-day battery life. The smartwatch is available for pre-order starting at around $410.
