A Fitbit patent hints at blood pressure technology in a future smartwatch

Future Fitbit wearables like the Fitbit Versa 4 smartwatch could feature built-in blood pressure sensing technology, according to a patent filed by Fitbit that came to light this week.

Patent (opens in a new tab) (By Edge (opens in a new tab)) describes a system that “calculates a blood pressure estimate from one or more samples of sensor data”, with the user placing one finger on the wearable device display to obtain the reading.

It would be a surprise if Fitbit wasn’t working on this kind of technology, and indeed we’ve seen prior research and previous company patents suggesting something like this was in the works. However, it will be difficult to get the right result.
