Development of an autonomous human-sensing system with MEMS devices

Continuous observation of human activities and circumstances are quite important to improve the QoL (Quality of Life). A small device that can collect a lot of data of the human conditions and circumstances by suing various MEMS (Micro Electro Mechanical Systems) sensors is very useful device to prevent the human accidents or troubles. The accidents especially happen to the professional driver or pilot e.g. the operator of the human centered transportation systems cause a serious accident. This study demonstrates a prototype development of an autonomous multi-environmental sensing device for human applications that can measure various time-based data, simultaneously. The measured data are stored in a micro SD card memory via an onboard microcontroller, which will be help for data analysis and preventing the accidents. The detailed configurations of the prototype device and some experimental results are also shown.
