Noncontact Sleep Monitoring System Under a Mattress

Sleep quality and duration are critical indicators of individual health. Traditional methods of monitoring them either were limited to the application environment or resulted in discomfort. To overcome these existing limitations, we propose a noncontact sleep monitoring system placed under the mattress, named SleepMatrix, to provide users with a comprehensive picture of their real-time to long-term health status. SleepMatrix is a sleep monitoring system that consists of two parts: a front-end sensor array and a cloud-edge data processing system. The data-driven system, based on the Internet of Things, can be flexibly deployed in environments from homes to transportation, and a variety of centralized control and monitoring functions can be flexibly deployed under different application scenarios. At the same time, users can view real-time and historical data through supporting applications and understand the sleep monitoring results. SleepMatrix is a complete and systematic sleep monitoring tool that can help people understand their health status and its evolution from a new perspective and therefore may contribute greatly to informing users of potential illnesses.
