Monitoring daily activity and load of human activity is important for maintaining health and preventing life-style related diseases or sudden death from overwork. We can evaluate quantitative activity and load with multiple sensors attached to the human body. In this study, we created a prototype system for measuring environmental conditions, including ambient temperature, pressure, humidity, and...
This study describes a human activity monitoring system that uses microelectromechanical systems (MEMS) sensors. The prototype system contains four sensors for ambient monitoring: 3-axis acceleration, barometric pressure, temperature, and relative humidity. The peripheral circuitry for each sensor is connected to a one-chip microprocessor. The measured data is stored in memory and transferred via...
