MEMS振動発電型イベントドリブンセンサを用いた橋梁の低消費電力異常周波数監視システム

抄録

We have developed a sensor for damage detection and abnormality notification using a MEMS vibrational energy harvester as an event-driven sensor picking up a specific frequency signature. Owing to a substantial power-saving performance, the monitoring system becomes almost maintenance-free for more than 10 years, thereby enabling efficient and reliable inspections of social infrastructure.
