Wearable Skin-tone Friendly Electronic Device for Cardiovascular Monitoring
Abstract:Current wearable smartwatch products mainly utilize photoplethysmography (PPG) sensing modules for pulse signal measurement to derive heart rate and blood pressure values. However, PPG signals are highly susceptible to variations in skin melanin levels, leading to inaccuracies in physiological measurements. In this study, we present a novel biomedical eddy current sensor (BECS)-based sensing module, which can be fully integrated within a smartwatch without requiring a specific sensing region on the watch case. Compared to conventional PPG-based smartwatch sensors, the proposed technique enables seamless integration into the smartwatch, addressing racial disparities in user measurement accuracy. Moreover, the design eliminates the need for a transparent sensing region at the bottom of the watchcase, thereby preserving the structural integrity and aesthetic appeal of the watch while simplifying its mechanical design. We are actively advancing this technology as a promising alternative to optical modalities, aiming to enhance wearable health monitoring and drive future innovations in the smartwatch industry.
