The measurement technique of human's bio-signals

Abstract

A disaster like a big earthquake usually brings many destroyed buildings and many sufferers are generated in the disaster area. In this situation, sometimes a rescue person encounters a second disaster. This is the big problem to rescue sufferers. In order to avoid a second disaster, many kind of rescue robots are being developed. These robots can find sufferers and rescue them. However, they cannot measure the sufferer's condition at the disaster area. If the sufferer's condition becomes clear before rescue, the rescue efficiency will improve. Therefore, we are developing a rescue robot that can measure some vital signs of sufferer and send measured data to the medical doctor who is in safety place. In this paper, we will describe about a developed method that can measure the pulse and the arterial blood oxygen saturation degree (SPO2) by easy way. We think that these methods will be powerful and useful to rescue sufferers.
