Wi-Fi signals and machine learning can noninvasively process heart rate with clinical-level accuracy in under 5 seconds. After being tested on 118 people, it read pulse during motion using a $30 ...

CSI sensing (Wi-Fi sensing), which uses Wi-Fi signals to estimate a person's location and posture, has been gaining attention. Recently, a research team at the University of California, Santa Cruz, ...

If you wear a smartwatch or fitness tracker, you probably already have access to a steady stream of data about your heart health. Beyond basic heart-rate monitoring, smartwatches and fitness trackers ...

High-frequency radar can detect extremely subtle body movements, such as those caused by the heart beating. In this study, researchers used millimeter-wave radar to remotely measure heart rate in two ...

Measuring the heart rate of great apes in captivity is essential for both health management and animal studies. However, existing most methods are either invasive or inaccurate. Now, researchers have ...

Computer Science and Engineering Ph.D. student Nayan Bhatia demonstrates Pulse-Fi, technology that uses WiFi signals to measure a person's heart rate. Heart rate is one of the most basic and important ...
