Development of the device to detect human's bio-signals by easy sensing

A disaster like a big earthquake usually destroys many buildings and generates many sufferers. 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 kinds 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, it makes rescue action more efficient and will be useful for the triage. So, we are investigating the measure system which can be installed on a rescue robot and obtain vital signs of sufferers easily at the disaster area. In this paper, we will describe developed methods that can measure ECG (Electrocardiogram) and SpO2 (the arterial blood oxygen saturation degree) by easy way. We think that these methods will be powerful and useful to rescue sufferers.
