Vital Sign Monitoring Through the Back Using an UWB Impulse Radar With Body Coupled Antennas

Abstract: Radar devices can be used in nonintrusive situations to monitor vital sign, through clothes or behind walls. By detecting and extracting body motion linked to physiological activity, accurate simultaneous estimations of both heart rate (HR) and respiration rate (RR) is possible. However, most research to date has focused on front monitoring of superficial motion of the chest. In this paper, body penetration of electromagnetic (EM) wave is investigated to perform back monitoring of human subjects. Using body-co… Show more

“…The SNR was improved as compared to Doppler and IR-UWB radar with a reflected waves feature. In article [87], researchers have designed a back antenna for vital signs measurement inside a vehicle. As the body reflective coefficient lies around 75%, it is hard to transmit the EM waves through the body tissue.…”

“…In 2010, Levitas used UWB radar to realize live person detection behind non-metallic obstacles [17]. In 2018, Schires proposed installing UWB in the driver's seat, which can accurately detect the respiration and heart rate, but it still has the problem of high cost and increases error caused by motion artifact and clothes [18]. In comparison, since it is unnecessary to consider the requirements of high switching speed and high delay precision of an integrated chip in a UWB radar system, continous wave (CW) radar has a simpler structure.…”

“…The remote monitoring module is able to track real time information of the physical condition as well as movements. Sensors are integrated into many types of radio wave devices such as capsules, textile and elastic bands, and are implanted or directly adhered to human skin in combination with external devices for wireless monitoring of heart rate [6][7][8], vital signs [9], blood pressure [10,11], body temperature [12], electrocardiograms [13][14][15][16][17] and so on.…”
