Huawei's D2 smartwatch monitors your blood pressure – Apple, take note

There are several blood pressure monitors on the market, but few reliable smartwatches with that functionality. Chinese tech brand Huawei’s Watch D2 could change that.

Huawei’s Watch D2 includes an ambulatory blood pressure monitoring device, the first wrist-based device of its kind. The wearable is certified by China’s National Medical Products Association and the EU’s Medical Device Regulation. According to Huawei, the device is one-fifth the width and 1/25th the volume of a traditional electronic blood pressure monitor, designed with portability and continuity in mind. The smartwatch is not for sale in the US.

The smartwatch can measure blood pressure at pre-set intervals for 24 hours to calculate averages and BP rhythms, supplemented by its TruSense System for improved speed and accuracy. This sort of blood pressure monitoring occurring over a day can help those with hypertension and cardiovascular issues get a clearer picture of their blood pressure for longer than a typical doctor’s visit. 

Several smartwatches have blood pressure monitor capabilities but require extra equipment. For example, Samsung’s Galaxy Watch 7 can track your blood pressure with the help of the Samsung Health Monitor app; however, to use the feature, you need to calibrate it with a cuff-based blood pressure monitor. Samsung’s wearable also hasn’t received FDA approval as a BPM, so it can’t be used for diagnosis or treatment. The Apple Watch can aggregate your blood pressure data in its device but can’t take measurements itself. 

The blood pressure monitor market is expected to grow within the next few years. Fortune Business Insights estimates a 9.2% compound annual growth rate for the market size from 2025 through 2032. Cardiac arrhythmia and hypertension, among other diseases, have fueled the demand for these devices. 

Bloomberg’s Mark Gurman says that a blood pressure monitoring device could come to the Apple Watch Ultra 3 this year, though the feature was previously delayed, so who knows when it will come. If implemented in Apple’s next-gen smartwatch, the feature and its widespread use could detect hypertension (high blood pressure), an often undetected condition that leads to other health complications.
