Abstract

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.
