OPPO has received a patent that might revolutionize the way blood pressure monitoring systems are integrated into smartwatches. This patent, filed with the World Intellectual Property Organization (WIPO), describes a more straightforward and efficient way to measure blood pressure.
Downsides of Existing Technology
Smartwatches, such as the Huawei Watch D2, utilize an airbag within the strap for blood pressure measurements. This airbag is inflated by an air pump located in the watch head, connected through an air nozzle. While this method works, it comes with a major downside: the air nozzle occupies space in the watch head, which restricts the arrangement of other parts, including additional sensors.
How OPPO’s Innovative System Operates
The innovative patent from OPPO removes the need for a separate air nozzle by integrating the air path directly into the strap of the watch. In this design, the watch head contains an air pump along with a shell assembly that links to the strap through a “connecting assembly.” This connection completes the air path, allowing for the airbag to be inflated and deflated without the requirement for a separate nozzle.
This new design not only simplifies the manufacturing process but also enhances the arrangement options for internal components. It opens up more space within the watch head, enabling more compact and versatile designs.
Future of OPPO’s Smartwatches
Even though OPPO has been awarded the patent, it remains uncertain when the company will launch this technology in its smartwatches. There are reports stating that the upcoming OPPO Watch X2 may include blood pressure monitoring capabilities, but it’s yet to be confirmed whether this particular system will be utilized.
Regarding the Watch X2, current reports indicate that it will be available in three distinct models: the standard Watch X2, a larger 46mm version, and the premium Watch X2 Pro, with some models potentially being rebranded as the OnePlus Watch 3 internationally. Notable features of these models are blood pressure and ECG monitoring, wrist temperature assessment, a 60-second health check, and fitness tracking with GPS functionality.
