Abstract :
Sleep age and sleep index are defined based on heartbeat and body movement measured noninvasively by the pneumatic method for a person sleeping in bed. Sleep age indicates the quality of sleep, and sleep index shows the temporal changes in sleep conditions, by which the sleep stage of the R-K method can be estimated. The overall sleep stages estimated by the proposed method show similar sleep characteristics to those obtained by the R-K method and show reasonable sleep transition
