Abstract:
Structural health monitoring technology uses advanced sensors to collect structural state data inreal time, evaluate its integrity and residual life, and make maintenance decisions accordingly. The keyof structural health monitoring is to obtain structural data accurately. With the development of new sensortechnology, sensors and data acquisition devices for structural health monitoring are constantly emerging,and the performance of these devices is developing rapidly. The latest developments of fiber opticsensors, piezoelectric material sensors and self-diagnostic sensors for structural health monitoring aresummarized. The basic working principle of each sensor and its application in structural health monitoringare introduced, and the challenges and opportunities faced by sensors in structural health monitoring areprospected.
