A Study of Vital Signs Monitoring Mobility Robot Based on mm-Wave FMCW Radar

Most conventional radar-based remote heart rate measurements require the subject to remain stationary. Secondly, the valid measurement range is limited by radar module specifications. Furthermore, the accuracy decreases when the subject is far from the radar. Therefore, this article proposes a novel remote heart rate measurement method based on radar and a mobility robot. The method adaptively adjusts the radar to be in an appropriate measurement range to measure heart rate while the subject walks. The experimental results demonstrate the feasibility of the proposed method.
