Radar Monitoring Vital Signs

Researchers at the University of Waterloo (Canada) assert this: “we use a frequency modulated continuous wave (FMCW) radar operating at 77 GHz in a bedroom environment to extract the respiration and heart rates of a patient, who is used to lying down on the bed. Indeed, the proposed signal processing contains advanced phase unwrapping manipulation, which is unique. In addition, the results are compared with a reliable reference sensor. Our results show that the correlations between the reference sensor and the radar estimates are in 94% and 80% for breathing and heart rates, respectively.” For nursing homes and even e-ICU units, radar monitoring preserves patient privacy where a camera isn’t required.
