Abstract

Solitary death of elderly people is recognized as social problem in Japan. There is a real need for a new device to monitor the health condition of elderly people. In this study, we made a health monitoring system by measuring a body conduction sound. The system consists of a measurement device and a server. The device consists of a body conduction sound sensor, a microcontroller and a Wi-Fi module. The server indicates the measurement result as a graph and derives the pulse rate from the autocorrelation result of the measurement data. The measurement data are sent to the separated server using Wireless LAN. The efficacy of the system is confirmed by the measurement of a body conduction sound.
