Scientists at Kyoto University have come up with a way of measuring heartbeats wirelessly.
According to Wired, sensors pick up signals from the body using millimeter-wave spread-spectrum radar technology. The researchers claim that it's as accurate as an electrocardiograph.
"The body sends out all sorts of signals at once, including breathing and body movement," said Toru Sato, a member of the team who worked on the project. "Our algorithm extracts waves characteristic of heartbeats from the chaotic radar signal and calculates their intervals."
"Taking measurements with sensors on the body can be stressful and troublesome," said lead researcher Hiroyuki Sakai. "We tried to make something that would offer people a way to monitor their body in a casual and relaxed environment."
