Outline of Final Research Achievements

After the Great East Japan Earthquake, it is important to establish advanced maintenance strategies of infrastructures, such as elevated tracks, tunnels, bridges used in railway and roads. The purpose of this study is to develop a remote monitoring system that makes it possible to detect and to characterize degradation level of structured ferromagnetic materials. The final goal is to construct a quantitative evaluation method starting from early detection of anomalies to continuous surveillance of material defect process using magnetic sensor networks.
