Zusammenfassung:	A crack detecting system includes a tool movable along a conduit or structure and having at least one sensing device for sensing cracks in a wall of the conduit or structure. The tool includes at least one component that includes a metamaterial. The system includes an emitting source that has at least one transducer. A processor is operable to process an output of the at least one sensing device. The processor responsively determines cracks present at the wall of the conduit or structure via the processed output.
