Universiteit Kyoto en Panasonic ontwikkelen nieuwe technologie voor hartmetingen op afstand
KYOTO & OSAKA, Japan–(BUSINESS WIRE)– De universiteit van Kyoto en Panasonic Corporation hebben vandaag bekendgemaakt dat ze een nieuwe waarnemingstechnologie hebben ontwikkeld voor het op afstand controleren van vitale signalen, zoals hartslag, de interval tussen hartslagen en andere zaken. De technologie bestaat uit een zeer gevoelige radar met gespreid spectrum en een algoritme dat op basis van bewegingen de tijd tussen hartslagen schat. Dit maakt directe metingen van de hartslag en de hartslaginterval met de accuratesse van een elektrocardiogram mogelijk, zonder dat sensoren op het lichaam zijn vereist.
De technologie maakt de ontwikkeling van ‘alledaagse waarneming’ mogelijk – metingen gedurende dagelijkse bezigheden van personen, als ze bijvoorbeeld gaan slapen of zich klaarmaken voor een nieuwe dag.

KYOTO & OSAKA, Japan–(BUSINESS WIRE)– Kyoto University and Panasonic Corporation today announced that they developed a new remote sensing technology for vital signs such as heart rate, heartbeat interval and others. This technology consists of high sensitive spread-spectrum radar and feature-based heartbeat interval estimation algorithm, and enables to measure heart rate and its intervals in real time without placing sensors on the body with as high accuracy as electrocardiographs.

The remote sensing system combines millimeter-wave spread-spectrum radar technology and a unique signal analysis algorithm that identifies signals from the body. “Heartbeats aren’t the only signals the radar catches. The body sends out all sorts of signals at once, including breathing and body movement. It’s a chaotic soup of information,” says Toru Sato, professor of communications and computer engineering at Kyoto University. “Our algorithm differentiates all of that. It focuses on the features of waves including heart beats from the radar signal and calculates their intervals.” The team hopes that the remote sensing system, with further experimentation, will be put to practical use in the near future. “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,” Sato concluded.
