Development of the Bathroom Watching System Supported by the Breath Detection

Abstract

Recently, domestic accidents caused by sudden illness are increasing in Japan. We developed a detection and alarming system for the dangerous state in a bathroom. FG sensor which has been developed in our laboratory is used in this system to get respiratory information of bathing person. It becomes possible to watch the person in a bathroom by this sensor, without invading his privacy. We applied the developed system to an actual bathroom, and carried out several experiments supposing various situations. As a result of the experiment, we confirmed that this system can acquire the person's respiratory information and can emit alarms correctly for emergency.
