In fact, a patent discovered by AppleInsider has revealed that Apple is exploring ways to bring blood pressure monitoring to the Apple Watch, and one of those ways could come in the form of a stretchable Apple Watch band that comes with an inflatable bladder.
According to the patent’s description, “A user may monitor one or more of their physiological parameters by attaching a monitoring device such as a blood pressure monitor to one of their limbs. The blood pressure monitor may include an inextensible cuff that secures an inflatable bladder against a limb of the user.”
This means that users who have a need for constant blood pressure monitoring might need to use the band at all times. The upside to this is that it might offer more accurate readings, but the downside is that users might have less options when it comes to aesthetics.
Samsung’s Galaxy Watch 4 actually offers blood pressure monitoring, but it does require the occasional recalibration with an actual blood pressure monitor, so maybe Apple is looking for a better solution. Word on the street is that blood pressure monitoring could be a feature of the Series 8 in 2022, but whether it will come in the form of an inflatable and stretchable band remains to be seen.
