Abstract
Monitoring vital signs regularly helps the early recognition of abnormal physiological parameters in deteriorating patients. Impulse radio ultra-wideband (IR-UWB) technology is a suitable non-invasive approach to monitor the vital signs such as heart and breathing rates. In this technique, the IR-UWB radar antenna propagates signal towards the patient and the reflected spectrum can determine the status of the vital signs. This function is ideal where patient touching should be avoided such as a potentially infected COVID-19 patients. This paper designs an algorithm to identify the chest displacement and to separate the heart and breathing signals. In addition, we propose an adaptive filter and a smoothing filter used in the function to reduce the measurement noise from the surrounding vibrations. We have implemented the device and validated the performance over different sets of real experiments. The results show that the proposed technology can effectively estimate the breathing and heart rates with up to 98% accuracy as compared to the values obtained using an electrocardiograph (ECG).
