Japan-based Panasonic in collaboration with Kyoto University has developed a new remote-sensing technology to measure vital signs such as heart-rate, heartbeat interval and others.
The new remote-sensing system is a combination of millimetre-wave spread-spectrum radar technology and signal analysis algorithm, which identifies signals from the body.
The technology comprises of high-sensitive spread-spectrum radar and feature-based heartbeat interval estimation algorithm.
It allows measurement of heart-rate and its intervals in real-time without placing sensors on the body with as high-accuracy as electrocardiographs.
Panasonic researcher Hiroyuki Sakai said: "Taking measurements with sensors on the body can be stressful and troublesome, because you have to stop what you're doing.
"What we tried to make was something that would offer people a way to monitor their body in a casual and relaxed environment."
The new technology enables casual sensing of vital information such as pulse rate and heartbeat interval remotely, helping in daily health management.
The company said that the remote-sensing technology enables people to monitor their health status for their own benefit.
Kyoto University communications and computer engineering professor Toru Sato said: "Our algorithm differentiates all of that. It focuses on the features of waves including heartbeats 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."
Last November, Panasonic introduced new 4K medical-grade 32 ultra-high-definition (UHD) monitor, designed for the surgical suite.
The new 4K UHD surgical monitor offers 3,840px x 2,160px resolution, providing double the total pixels of a 2K monitor and is fully compliant with medical equipment standards.
