Application of Multi-Environmental Sensing System in MEMS Technology - Monitoring of Human Activity

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 three-dimensional acceleration (shock) sensing devices, using MEMS technology. The prototype can continually monitor and record environmental conditions and provide the history of the body´s activity and environmental load quantitatively. In this paper, we detail the system configuration and characteristics, and provide the examples of measured data.
