Smart Sensors and Wireless Technology for Scrutinizing Civil Infrastructure

As the human civilization is growing day by day, the nations are making huge investments in infrastructure and its provision or service ability. Now a days, it becomes very important to monitor the conditions or serviceability of these civil infrastructure in time due to everyday abrasion caused by nature calamities, physical or chemical actions. For this purpose structural health monitoring has been taken into consideration for endowment of information about the situation of civil structures, but estimation of the structural condition or state is quite a challenging task. While the research & work on structural health monitoring is still going on, a smart sensor offers new opportunities for structural health monitoring. To realize structural health monitoring, employing smart sensor system needs to be designed considering both the characteristic of smart sensor & the structure to be monitored. This paper present an idea about smart sensor, their generation and how these to be employed and controlled in the structural health monitoring.
