Abstract
Natural disaster rages in recent years, and this damage tends to increase by influence of global warming. At the time of a disaster, not only victims but also rescuers are caught up in a disaster. This phenomenon is called the second disaster, and now some rescue robots are developed to prevent this disaster. Therefore, in this study, I developed the device which is able to set on the rescue robot, acquires a pulse wave of victims which is one of the bio-signals by easy sensing and detects Arterial Oxygen Saturation with the rescue robot to realize more effective rescue operations with grasping conditions.
