Panasonic, Kyoto University unveil radar-based remote vital sign sensor
Kyoto University and Panasonic have revealed a novel vital-sign-sensing technology that's based
"Taking measurements with sensors on the body can be stressful and troublesome, because you have to stop what you're doing," said Panasonic researcher Hiroyuki Sakai in a statement. "What we tried to make was something that would offer people a way to monitor their body in a casual and relaxed environment."
The radar-based vital sign monitoring system is expected to be part of technology enabling individuals to monitor their own health. It combines millimeter-wave spread-spectrum radar technology with a signal analysis algorithm that identifies signals from the body.
"Heartbeats aren't the only signals the radar catches," said Toru Sato, a professor of communications and computer engineering at Kyoto University. "The body sends out all sorts of signals at once, including breathing and body movement. It's a chaotic soup of information. Our algorithm differentiates all of that. It focuses on the features of waves including heart beats from the radar signal and calculates their intervals. Now that we know that remote sensing is possible, we'll need to make the measurement ability more robust so that the system can monitor subjects in various age ranges and in many different contexts."
