This special issue reviews some recent progress in non-destructive inspection (NDI) technology. Some accidents and failures of infrastructures have been reported recently. It is very important to minimize environment load in order to realize a sustainable society, and one of most effective approaches is to extend the life of infrastructures using NDI technology. A lot of new technologies are developing to replace energy derived from fossil fuel. NDI also plays an important role to keep integrity of new types of structures as well as controlling materials process. Structural health monitoring and global sensing with networking are key-words to realize sustainable society supported by NDI.
