Dai Nippon Printing has developed a passive adhesive sheet with a built-in Identiv UHF RFID tag, to detect when a crack to which a sheet is affixed widens, and to transmit that event when interrogated.

Japanese construction companies have been testing a new RFID-enabled product that automates the inspection of infrastructure cracks, with a goal of preventing catastrophic failures to bridges, tunnels or other structures. Dai Nippon Printing Co. (DNP) developed a new tag that employs passive ultrahigh-frequency (UHF) RFID technology to monitor the conditions of structures as they age. The tag has a built-in Identiv UHF RFID inlay that transmits a unique ID number when interrogated, but that ceases working properly when damaged by the expansion of a small crack on a structure to which it is attached.
