Abstract

Long-term and continuous vital sign monitoring is essential for the early detection of hypertension. Blood pressure sensing based on non-contact biological measurement indices such as photoplethysmograms and skin temperature that can be obtained using visible light and infrared images has been attempted in previous studies. Near-infrared light has high transmissivity to living tissues and has been used for measuring arterial oxygen saturation. This study aims to improve the accuracy of non-contact blood pressure sensing using near-infrared light.
