Why the study?
Conventional radar-based remote heart rate measurements require subjects to remain stationary, have limited measurement ranges, and lose accuracy at greater distances.
A novel mobility robot equipped with mm-Wave FMCW radar can feasibly measure heart rate remotely in walking subjects.
Robot-assisted radar enables ambulatory remote monitoring; leaves open clinical validation before cardiovascular use.
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.
