New Smart Ring Says It Can Deliver Accurate Blood Pressure Tracking Without a Cuff
Startup Vital Signals has launched the Signal Ring, a wearable device claiming to track blood pressure continuously without a cuff. While the company cites clinical study data, medical experts remain skeptical, noting potential accuracy issues with the underlying light-sensor technology.
Why it matters
If proven accurate, this technology could revolutionize hypertension management by providing a non-invasive, convenient alternative to traditional blood pressure monitoring.
A brand-new smart ring, the Signal Ring , launched Thursday with an ambitious promise to continuously track blood pressure without an inflatable cuff or calibration. That's something no other smart ring currently offers.
Designed to work four to five times faster than traditional blood pressure cuff trackers, the Signal Ring, created by startup company Vital Signals, was tested in a 451-person clinical study with additional studies underway, according to a press release announcing the launch . The company says the device, which pairs with an app to provide the readings, meets "the international accuracy standard for blood pressure cuffs."
