Wi-Fi Heart Rate: UC Santa Cruz Scientists Unveil Pulse-Fi
Scientists at the University of California, Santa Cruz, have created a groundbreaking technology called Pulse-Fi. This innovative system uses everyday Wi-Fi signals to measure normal heart rate with remarkable precision.
Pulse-Fi works by detecting subtle fluctuations in Wi-Fi signals caused by a person's heartbeat. Researchers have developed a machine learning algorithm to interpret these fluctuations accurately. The system can measure normal heart rate in just a few seconds, regardless of the individual's position or the router's location, as long as they are within three meters of the router.
The team, whose names are not specified, used affordable chips like ESP32-SoC and Raspberry Pi for their experiments. They achieved clinical accuracy using commercial Wi-Fi routers, with potential for further improvement. Currently, Pulse-Fi can measure normal heart rate with the same precision as traditional methods. Moreover, researchers are exploring its potential to detect breathing rates, which could aid in identifying conditions like sleep apnea.
Pulse-Fi offers a non-invasive, convenient, and cost-effective way to monitor heart health. It could transform how we track vital signs, making it easier to detect issues like arrhythmias. As research continues, Pulse-Fi's potential to measure breathing rates could expand its applications in healthcare.
