Oral wearable sensors: Health management based on the oral cavity

Abstract

Wearable sensors have garnered considerable interest from humans over the past decades owing to their broad application prospects and huge development potential. Yet the limited number of reliable noninvasive wearable sensors has greatly hindered the progress of wearable sensors in the field of health management. Because of its good adaptability, physiology significance and abundant of biomarkers, the oral cavity, as one of the ideal positions for health monitoring using wearable sensors, is suitable for diverse biomedical applications. This paper presents a review of oral wearable sensors as real-time indicators of users’ physical condition by monitoring dental disease, salivary biochemical parameters, and food intake. The key opportunities and challenges toward the development of oral wearable sensors are also discussed. With continued studies and innovation to crucial challenges, such oral wearable sensors are expected to make contributions to personal health-care monitoring, and thus upgrading the current status quo of health management.
