Noninvasive Continuous Blood Pressure Measurement with Wearable Millimeter Wave Device

Wearable monitors for measuring vital signs such as blood pressure will greatly impact the medical field. This work presents a millimeter-wave, radar-based system for performing accurate measurements of systolic and diastolic blood pressure at the radial artery. A 120-subject study was conducted to assess the feasibility of the proposed approach. Blood pressure was determined using a one-time initialization process that converts radar output into pressure units (in mmHg). Measured systolic and diastolic blood pressure values against a clinical reference device show promise for beat-to-beat blood pressure measurement in a variety of healthcare settings.
