Chinese manufacturer Oppo, which also makes the OnePlus range of Android phones and wearables, looks set to debut a new watch next month, likely to be the OnePlus Watch 3. A promotional image, shared on Weibo by OPPO product manager Zhou Yibao, showcases a cool new feature: blood pressure monitoring, indicating hypertension risk.
Accurate blood pressure monitoring via LEDs remains a “holy grail” health feature for even the best smartwatches, proving frustratingly out of reach. The Huawei Watch D2 is the most accurate so far, including in its technology a strap packed with inflatable bladders, acting as a portable blood pressure cuff.
