Abstract

Civil infrastructures are normally one of the most expensive investments in a nation. To ensure the security of our homeland, the integrity of critical infrastructural systems must be assessed periodically. The assessment of the performance and reliability of the infrastructures can be carried out effectively and efficiently through the use of a network of smart sensors. The smart sensors will constantly interrogate the state of the structural health and detect any initiation or progression of damage in the infrastructures. Proper warnings can be issued prior to structural failure to prevent catastrophic loss of lives and properties. In addition, the infrastructural health monitoring system can request a comprehensive structural performance re-evaluation when the deterioration of the structure has threatened the integrity. This paper reviews the current state of the art on applying smart piezoelectric sensors in infrastructural health monitoring. Experimental results for using smart sensors to detect the damage on some typical infrastructural components are presented. With the goal of constructing an automated on-line structural health monitoring system to constantly assess the integrity of critical infrastructural systems, this paper illustrated the promise of using the smart piezoelectric sensors in homeland security.
