Abstract :
So far, sleep has been measured by attaching various apparatuses to the body such as EEG and ECG. In this study, to judge the sleep depth, vital signals detected by the pneumatic pressure sensor are used, in which no contacting to the human body is necessary. The purpose of this paper is, therefore, to analyze the sleep depth from the measurements, and to provide information to improve the sleep.
