The COVID-19 pandemic has significantly impacted several populations, partially due to the lack of access to basic health care amenities, and emphasized the need for continuous telehealth monitoring of relevant biometric vitals. This need is further emphasized through research that has suggested that simple biometric vitals, including heart rate (HR), blood oxygen saturation rate (SpO2), and temperature, are relevant biomarkers for early disease diagnosis. The project aims to address this need through the design wearable health platform that uses novel, non-invasive techniques to monitor biometrics with the eventual goal to provide user insights into current health status and identify early stages of illness associated with COVID-19. This wearable utilizes PPG and temperature sensing technology in order to provide accurate measurements of the three aforementioned vitals: temperature, heart rate, and blood oxygen saturation (SpO2). Our system has shown promise early in development, having only marginal differences in heart rate measurements with comparable commercial sensors (0.17%-3.92%). Further work would include improvement of SpO2 calculation, physical and electrical design improvements, and completion of end-to-end integration for a more cohesive project.
