A Wearable mmWave Radar System for Continuous Cardiopulmonary Monitoring

A 60 GHz wearable radar system is introduced for the first time for the continuous monitoring of human respiratory patterns and cardiac waveforms, including the detection of the respiratory rate (RR) and heart rate (HR). Full-wave electromagnetic simulations are presented to investigate the performance of the radar antennas in close proximity to a human subject. A physical prototype was developed, and a measurement campaign shows high accuracy levels for RR and HR detection, with cardiac displacement waveforms being mapped successfully against a standard electrocardiogram (ECG).
