Abstract—In a super-aged society, medical services for health management have various problems. To solve these problems, it is desirable for all generations, including the elderly, to be self-reliant and maintain their health. In this paper, a system is proposed for everyone to actively manage their health. This system uses various contactless sensors to monitor the health of the elderly living alone and monitor and store the biometric information of the person. By comprehensively analyzing these sensor data, the system assists people and observers to easily recognize changes in the physical condition of the target person. Further, the system facilitates providing information to distant healthcare professionals when people receive medical care at home. The system prototype was created to demonstrate this mechanism. Also, the system conducts preliminary experiments and confirmed that the models and algorithms worked as expected. In the demonstration experiment, the observation target was observed using a millimeter-wave sensor and a multi-channel gas sensor, and both were integrated. As a result, the system presents changes in the observation target in detail.
