Fitbit Patent Hints at Blood Pressure Monitoring: The Health Tech industry is a fast-growing space where brands keep advancing personal wellness tracking. Wearables have evolved beyond simple step and heart-rate counting, and are now seeking richer health insights. A new patent application looks to showcase some of the features being tested for next-gen devices, including blood pressure (BP) monitoring — a total game-changer for Fitbit. This trend aligns with the conventional paradigm of non-invasive health inferencing.

Fitbit’s New Patent Suggests Blood Pressure Monitoring for Future Smartwatches and Smart Rings

Now, Android Central has uncovered a new patent that outlines the way Fitbit might pull off this trick. The filing describes a wearable with pressure and optical sensors that can measure changes in blood flow and arterial stiffness. This approach aims to recreate the conventional cuff BP measurements without bulky equipment. The patent indicates that the tech could be applied to a smartwatch or even a smart ring, allowing for constant and unobtrusive tracking.

As it passes through the blood vessels, some of the arterial information comes up between the mechanical and optical, so that together, from the mechanical movement of blood, it understands the BP data. Fitbit also suggests incorporating self-inflate or mechanically actuate components built into the wearable as a substitute for the pressure exertion of traditional BP units.

This isn’t Fitbit’s first foray into BP tracking. The company also filed a similar patent in 2023, but there’s no such feature in any of its current devices. Fitbit is not the only company pursuing BP monitoring in wearables. Although some smartwatches are introduced with this ability by Samsung, regulatory approval, FDA clearance, is a considerable challenge. Research is also ongoing to ensure accuracy and reliability.

Many brands, including those that are big in India, have tried to incorporate the functionality in smartwatches but data accuracy concerns have limited adoption. If Fitbit’s technology proves effective and gains regulatory approval, it could provide a reliable solution for regular blood pressure tracking. This innovation may help users manage their health better and contribute to early detection and prevention of hypertension-related issues, ultimately saving lives.
