Dynamic Measurement of Body Inclination in Walking by Body Area Network Sensing System

This paper shows the dynamic measurement system and result of body inclination in walking by monitoring acceleration at waist. To monitor the acceleration in walking, the sensing system had been constructed as a wearable and small scale wireless network system (body area network sensing system (BANSS)) put on body. BANSS is constructed with a host system and plural sensing nodes. Sensing node has sensors, microprocessor and near field communication device (NFCD). In this study, the sensing node measures the acceleration at waist of user in walking, and sends them to the host system regularly. By analysing the acceleration data at host system, the situation of body inclination in walking was estimated dynamically. It has been confirmed that the body inclination generates for everybody regardless their consciousness.
