Abstract :
In this study, a new automatic sleep stage judgment system was proposed using a non-invasive type air mattress sensor enabling the detection of three useful bio-signals: heartbeat rate, respiratory rate and other body movement. We found that fairly good correlations exist between these signals and the sleep stage. Based on this knowledge, we developed a novel sleep estimation method free from any stress.
