Design outcomes

Primary

Measure	Time frame
Detection accuracy of sleep stage 2 and sleep stage 3 emergence timing evaluated using Kyocera blood flow and acceleration sensors	—

Secondary

Measure	Time frame
1. Sleep stages obtained by visual sleep staging by a clinical laboratory technician after obtaining biometric data from electroencephalography, electrooculography, electromyography, etc. of polysomnography 2. Kyocera's blood flow and acceleration sensors to be developed by Kyocera to evaluate the feeling of wearing them, their effect on sleep, etc. 3. Questionnaires (Morningness Eveningness Questionnaire, Pittsburgh Sleep Quality Index, OSA sleep inventory) 4. Evaluation of sleep with MotionWatch 8 by CamNtech Ltd and Oura Ring 3 by Oura Health Oy.	—
