Cardiovascular disease (CVD) affects over 1.3 billion people worldwide, further driving the demand for comfortable home blood pressure monitoring (HBPM). To overcome the limitations of traditional cuff-based devices (intermittent measurement, motion artefacts), this study proposes an electromagnetic-based cuffless blood pressure monitoring (EM-BPM) system that uses non-contact radio frequency/microwave sensing to detect vascular wall motion via Faraday’s law. Key innovations include: A novel vascular deformation correction model (Eqs. 2 and 3), integrating radial strain (ε), Young’s modulus (E), and vascular geometric parameters (h, r0) to achieve accurate hemodynamic parameter inversion; and a medical-grade five-layer architecture that integrates optimised RF transceivers, motion-resistant digital signal processing algorithms, microcontroller-based calibration, Bluetooth Low Energy/Wi-Fi connectivity, and embedded regulatory protocols (IEC 60601–1/ISO 81060/GDPR); This study establishes a foundational framework for clinical-grade HBPM, addressing critical technical gaps in continuous monitoring for elderly populations and chronic disease management.

摘要

Cardiovascular disease (CVD) affects over 1.3 billion people worldwide, further driving the demand for comfortable home blood pressure monitoring (HBPM). To overcome the limitations of traditional cuff-based devices (intermittent measurement, motion artefacts), this study proposes an electromagnetic-based cuffless blood pressure monitoring (EM-BPM) system that uses non-contact radio frequency/microwave sensing to detect vascular wall motion via Faraday’s law. Key innovations include: A novel vascular deformation correction model (Eqs. 2 and 3), integrating radial strain (ε), Young’s modulus (E), and vascular geometric parameters (h, r0) to achieve accurate hemodynamic parameter inversion; and a medical-grade five-layer architecture that integrates optimised RF transceivers, motion-resistant digital signal processing algorithms, microcontroller-based calibration, Bluetooth Low Energy/Wi-Fi connectivity, and embedded regulatory protocols (IEC 60601–1/ISO 81060/GDPR); This study establishes a foundational framework for clinical-grade HBPM, addressing critical technical gaps in continuous monitoring for elderly populations and chronic disease management.
