Does a millimeter-wave radar-based system accurately measure arterial pulse waveforms compared to a reference tonometer in human subjects?
A novel millimeter-wave radar system provides contactless arterial pulse measurements that strongly correlate with reference tonometry, offering a promising approach for wearable blood pressure tracking.
Johnson et al. (2019) studied this question. Millimeter-wave, radar-based system vs. Reference tonometer was evaluated on Correlation between waveforms and spectral signatures compared to a reference tonometer. A wearable millimeter-wave radar system successfully measured radial arterial waveforms with strong correlation to a reference tonometer, demonstrating feasibility for contactless pulse detection.
