Work-in-Progress: Bio Radar for Remotely Vital Sign Monitoring

Abstract

Contactless detection of heart and breathing rate is very impressive and interesting technology in biomedical field. This technology can play a vital role in life saving in different scenarios. For example, the burnt patients mostly suffer significantly with pain when ECG machine electrodes are hanged with finger and/or with chest. Thus, in this paper, we propose a contactless bio sensing apparatus, i.e., ultra-sonic bio radar, to detect the heart and breathing rates remotely. We aim to obtain these vital signs of human without any physical contact of the device with a human body by detecting the Doppler frequency shift in the received electromagnetic signal. Furthermore, the proposed approach can be also used for life detection buried under the debris in any disaster area. Since the work is still in progress, the results obtained so far indicate that the proposed method has capability to find the desired vital signs.
