Blood Pressure Monitoring Gets Personal The latest entry in the wearable tech market is Vital Signals' Signal Ring, a blood pressure monitoring device that promises to revolutionize the way we track our vital signs.
The ring's most notable feature is its ability to operate without calibration or subscription fees, a departure from traditional cuff based methods.
Vital Signals claims the Signal Ring's sensors can measure heart rate and blood pressure four to five times faster than other cuffless trackers, allowing for more detailed readings of the pulse wave the rhythmic swelling and contraction of arteries as the heart pumps blood.
