Abstract:
Physiological monitoring devices in modern clinical area are basical y used electrodes or sensors directly touching the surface of human subject body, which wil increase physiological and psychological load of the subjects. In order to realize non-contact monitoring of respiration and heartbeat, firstly, the micro bioradar was used to detect human body motion signal. Then, the respiration signal and heartbeat signal was extracted from the body-motion signal by using signal and conditioning circuits, digital filter and signal processing. Final y, the results of heart rate and breathing rate was wirelessly transmitted. The experimental results showed that the device for non-contact monitoring of respiration and heartbeat waveforms has advantages of smal volume, low power consumption, which can realize the monitoring of physiological parameters in real time.
