The Construction of M2M System with Sensor Networks Using Digital Plethysmograph Sensor

In recent years, the research of sensor networks advances and it is expected to be used in a wide variety of fields such as traceability system of products, environmental monitoring, health care, etc. We develop a M2M system with the sensor network technology for collection and analysis of the state of health and feedback of advices for better physical activity without human intervention. The system detects abnormality from pulse wave data from pulse wave sensor attached to the user. In this paper, we construct M2M sensor network system with continuous monitoring of arterial pulse wave and an advice generation function based on pr-installed rules, then we evaluate the usefulness of the system through experiment.
