Navigating sensor-skin coupling challenges in magnetic-based blood pressure monitoring: Innovations and clinical implications for hypertension and aortovascular disease management

Abstract

Non-invasive blood pressure monitoring has emerged as a critical frontier in cardiovascular healthcare, with magnetic sensors playing an increasingly pivotal role in wearable health technologies. This comprehensive review critically examines the complex challenges of sensor-skin coupling and its profound impact on the accuracy of blood pressure measurements in patients with hypertension and aortovascular disease. Despite the growing demand for precise, real-time health monitoring, significant limitations persist in current magnetic sensor technologies. Our analysis reveals how intricate interactions between sensor devices and skin characteristics including pigmentation, texture, and elasticity can substantially compromise measurement reliability. We systematically explore innovative approaches to mitigate these challenges, presenting cutting-edge strategies in advanced material development, adaptive calibration techniques, and sophisticated signal processing algorithms. The review synthesizes current research to demonstrate the multidisciplinary approaches necessary for enhancing magnetic sensor performance. By critically analyzing the nuanced interactions between sensor technologies and individual patient physiological profiles, we provide insights into developing more robust, personalized health monitoring systems. Our findings underscore the urgent need for continued innovation in non-invasive blood pressure monitoring, with direct implications for improved clinical assessment and patient outcomes in cardiovascular care.
