A photonic radar system has been developed by scientists that delivers contactless, high-definition detection of vital signs. It could be developed for use in ICUs, aged-care facilities, and for people with sleep apnea or infants with breathing concerns.

Using their newly developed and patented system, the researchers monitored cane toads and were able accurately to detect pauses in breathing patterns remotely. The system was also used on devices that simulate human breathing.

The scientists say this demonstrates a proof of principle for using photonic radar that could enable the vital-sign monitoring of multiple patients from a single, centralized station.

Photonic radar uses a light-based, photonics system — rather than traditional electronics — to generate, collect and process the radar signals. This approach allows for very wideband generation of radio frequency (RF) signals, offering highly precise and simultaneous, multiple tracking of subjects.
