Engineers have used artificial intelligence (AI) and cheap, off-the-shelf hardware to convert the amplitude of Wi-Fi signals into estimates of a person's heart rate.
The accuracy of this system, called Pulse-Fi, is remarkably consistent across body positions and distances, the researchers wrote in a study published Aug. 5 in the proceedings of the 2025 IEEE International Conference on Distributed Computing in Smart Systems and the Internet of Things (DCOSS-IoT).
