Key result
WaveBP enables contactless, beat-by-beat arterial blood pressure waveform estimation using commercial mmWave radar.
Why the study?
Routine blood pressure measurements are uncomfortable to repeat and usually provide only sparse systolic and diastolic readings, motivating an exploration of whether a commercial mmWave radar can recover the arterial pressure waveform beat by beat without body-attached sensors.

This study explores the feasibility of using a commercial millimeter-wave radar (WaveBP) to estimate the arterial blood pressure waveform beat-by-beat without body-attached sensors.
Blood pressure is central to cardiovascular assessment, yet routine measurements are uncomfortable to repeat and usually provide only sparse systolic and diastolic readings. WaveBP explores whether a commercial mmWave radar can recover the arterial pressure waveform beat by beat without attaching a sensor to the body.
