Pulse Wave Velocity Monitoring Using A mmWave Radar Network

Non-contact monitoring of vital signs has been increasing demand in healthcare applications. Monitoring biomarkers such as heart rate variability (HRV) or pulse wave velocity (PWV) in home scenarios is crucial for early detection of cardiovascular disease or the worsening of these diseases. This paper presents a mm Wave radar network to measure pulse transit time (PTT) and PWV without contact. The experiment is carried out measuring simultaneously the carotid, the heart and the femoral of a healthy subject. Results reflect that the system is capable of measuring the carotid-femoral PWV (cfPWV), which is the gold standard for measuring arterial stiffness.
