SensoRing: An Integrated Wearable System for Continuous Measurement of Physiological Biomarkers

摘要

Advancements in miniaturized electronics and smart sensors combined with a broad platform of smart phones, big data, cloud service and wireless communication have not only empowered wearable technology, they have also increased users life expectancy. This is done through a range of applications including; tracking physical activity, personalized health care, and recommendations for enhancing user experience. However, the ability to measure one's emotional state using wearable biosensors in healthcare applications has been limited due to several challenges related to a lack in comfort, accuracy, reliability and low-power consumption. In this paper, we presented a novel wearable ring sensor for the continuous measurement of four SNS activities: Electrodermal activity (EDA), heart rate, skin temperature and locomotion. Detailed information is given regarding the development of the proposed ring sensor followed by a discussion of the evaluation that was done utilizing the biosensor on volunteers to gather data. Specifically, volunteers wore the ring sensor while being simultaneously monitored with real- time telemetry and while going through different emotional states. The experiment demonstrated accurate results, and data were collected from 43 participants of diverse age, body mass, height, and race. Additionally, to evaluate the performance of the developed ring sensor, we compared the results with a state-of-the-art open source device. This research aims to improve the worn biomedical sensor market, specifically when it comes to size and accuracy of worn sensors.
