Abstract
Abstract This paper shows the possibility of using Ultrawideband (UWB) DW3000 transceivers for noninvasive vital sign monitoring via a transversal propagation method. The transceivers can provide a cheaper, more flexible, and easierto- apply measurement of vital signs than traditional electrocardiogram (ECG) devices. This will not substitute the common medical use but instead can make vital sign monitoring more accessible in other scenarios. Potential applications beyond clinical settings, like measuring the vital signs of a car driver, can be achieved. The primary focus of this study is the possibility of utilizing inexpensive UWB transceivers for ballistocardiography (BCG) measurements. The vital signs are measured on a small focus group to verify the results on a larger spectrum. A photoplethysmogram (PPG) device is used for reference measurement. The results show a great accuracy of 3 breaths per minute for respiration rate measurement. The heartbeat measurement shows an error mostly within 3 bpm due to the resolution of the proposed setup. Methods for further verification of the results, together with increasing the accuracy and resolution of the setup are proposed.
