To hear a pitter patter from afar: Catching heartbeats with millimeter-wave radar

20.01.2016

Kyoto University and Panasonic Corporation demonstrate new remote-sensing technology

Heartbeats can now be measured without placing sensors on the body, thanks to a new technology developed in Japan. Researchers at the Kyoto University Center of Innovation, together with Panasonic Corp, have come up with a way to measure heartbeats remotely, in real time, and under controlled conditions with as much accuracy as electrocardiographs.

The technology utilizes spread-spectrum radar to catch signals from the body and an algorithm that distinguishes heartbeats from other signals.

The researchers say this will allow for the development of "casual sensing" -- taking measurements as people go about their daily activities, for instance, when they are going to bed or getting ready to start the day.

"Taking measurements with sensors on the body can be stressful and troublesome, because you have to stop what you're doing," says Hiroyuki Sakai, a researcher at Panasonic. "What we tried to make was something that would offer people a way to monitor their body in a casual and relaxed environment."

The added convenience of remote sensing, the team believes, will be an incentive for people to monitor their health status for their own benefit.

The remote sensing system combines millimeter-wave spread-spectrum radar technology and a unique signal analysis algorithm that identify 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 extracts waves characteristic of 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.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
