Non-contact Doppler monitoring shows technical promise; leaves open clinical validation and accuracy in real-world settings.
A non-contact physiological signal monitoring system was proposed using Doppler radar sensor to detect the movement of human thoracic cavity. The system consists of Doppler radar sensor, signal conditioning, MCU data processing and wireless communication. The system collects human chest movement due to heart and respiration (pleura fretting signals for conditioning). The experimental results show that the Doppler radar that the system used with the zero phase IIR digital filter can achieve real-time monitoring, store the physiological data, separate respiration and heartbeat signals, eliminate the distortion of the signal phase and have advantages of small size, low power consumption, strong penetration.
