Evaluation of the Criteria for the Control of Arousal Level and Effect of Warning Signal

각성도 제어를 위한 평가기준의 설정 및 경고음의 효과분석

  • Published : 1997.03.01


This paper describes the development of portable arousal measurement and analysis system. Skin impedance change which responds to the change of arousal level was detected by the three elctrode constant current method and separated into two components(SIR, SIL). Relationship between Nz, IRI and arousal level was studied and criteria of arousal level control was decided by the sleep study. Measured data with and without warning signal were compared and analyzed.
