Radar-Based Contactless Patient Monitoring

Radar-Based Contactless Patient Monitoring
A radar-based remote monitoring system can accurately track a patient’s vitals non-invasively in uncontrolled settings.

Developed by a team from the University of Waterloo to monitor patients with sleep apnea, the system relies on radar waves sensitive enough to detect the slight changes in movement that correlate to breathing. The device was mounted on a ceiling over the patients’ beds, where it monitored the breathing of the volunteers with a 90 percent accuracy when compared to wired versions.

The team believes the contactless, radar-based system could have applications in routine monitoring of patients in long-term care homes and hospitals.
