Apple’s Patent Hints at Game-Changing Blood Pressure Monitoring

Apple is reportedly working on a new technology that may allow users to measure their blood pressure in a future iteration of the Apple watch.?

The company may leverage an innovative approach inspired by traditional blood pressure monitors, as detailed in a recently published patent by the US Patent and Trademark Office (USPTO).

This non-optical approach could rival existing methods from Huawei and Samsung, but its implementation timeline remains uncertain.

Apple could bring Blood Pressure monitoring to the Apple Watch using a newly patented technology.

How it Works

The patent outlines a system using an inflatable liquid-filled chamber, paired with a sensing chamber and pressure sensor, to detect Korotkoff sounds—vibrations produced when pressure blocks blood flow. Unlike conventional air-based systems, liquid chambers could offer greater measurement precision due to their incompressibility.

If realized, this innovation could deliver cuff-less, accurate blood pressure monitoring directly from the wrist. However, technical challenges and Apple’s history of unmaterialized patents mean there’s no guarantee this will feature in future Apple Watches.

While the patent doesn’t guarantee a launch, it signals the company’s commitment to redefining health tech. For now, it’s a waiting game.
