Hypothesis
Can mmWave radar effectively measure arterial pulse signals non-contactedly with stable morphology?
Conclusion
The study demonstrates that mmWave radar can reliably measure arterial pulse signals non-contactedly, achieving high correlation in pulse morphology across different body parts.
Supporting Evidence
- The pulse wave signals showed high consistency with a correlation of over 0.84 across different measurement times.
- Stable pulse morphology was achieved using a range–angle focusing algorithm.
- The study provides a reference for long-term pulse measurement using radar technology.
Takeaway
This study shows that a special radar can measure heartbeats without touching the skin, making it easier and more comfortable for people.
Methodology
The study used a MIMO array radar to capture arterial pulse wave signals from subjects' neck, chest, and abdomen, analyzing stability and repeatability over different measurement periods.
Limitations
Factors like age, body shape, and health status may affect measurement accuracy, and the technology faces challenges in large-scale studies.
Participant Demographics
Six subjects with normal heart conditions participated in the study.
