Structural Health Monitoring (SHM) provides real-time integrity monitoring of in-service structures to prolong their life and reduce maintenance cost. The Structure Health Monitoring system includes active sensing and passive sensing techniques:
Active Sensing – an excitation signal is sent to an actuator and other sensors pick up the structure response from the excitation signal. This type of sensing can detect damages on metal or composite structures including cracks, corrosion, delamination, debonding, etc.
Passive Sensing – all sensors listen to the structure response caused by impacts to the structure. This becomes useful for analyzing impact events and impact force-time history
By combining the active sensing and passive sensing technology together, a comprehensive scheme can be provided to detect any abnormally of the structure in real time. The same sensor network made of piezoelectric sensors is used for both the active and passive sensing.
