Application of MEMS-based Technologies to Bridge Monitoring

摘要

Rapid progress in MEMS (Micro Electro Mechanical System) technology produces elementtechnologies such as microprocessor, sensor and wireless module etc. with rich function, highaccuracy, low-cost and small-size. As a result, the possibility of realizing distributed sensor networkbecomes high. In particular, senor network using MEMS-based technologies has quite effect onmonitoring of spatially large-scale bridge. The objective of this research is to evaluate and applyMEMS-based technologies to bridge monitoring. Two topics will be discussed. One is a topic ofnewly supplied wireless LAN accelerometer. The other one is a topic of developing sensor nodeusing off-the-shelf MEMS element technologies.
