Identiv, Inc. announced that the company’s UHF RFID tags have been incorporated into a new system that monitors critical infrastructure and detects cracks in bridges and tunnels. The tag was developed for Identiv partner Dai Nippon Printing Co., Ltd (DNP), a comprehensive printing company based out of Japan, established in 1876.
Identiv’s UHF Tag portfolio is built around a comprehensive set of optimized designs for applications across industrial markets including asset tracking, logistics and parking access. UHF technology uses radio frequency spectra, which allow reading distances of several meters (equivalent to several dozen feet), depending on the size of the tags and the operating power transmitted by the UHF reader.
“In Japan, the majority of tunnels and bridges were built during the high economic growth period of the 1960s, meaning they are quickly becoming too old for continued use. We are seeing an increase in accidents due to decrepit concrete, which is a huge, dangerous problem,” said Sakae Hikita, DNP senior executive corporate officer. “Local government and transportation entities are under regulation to maintain inspections, however, the cost of such inspections is incredibly high due to complex testing equipment and the skill of the laborers performing such testing.”
In direct response to this growing issue, DNP partnered with Identiv and developed an infrastructure-monitoring RFID inlay that can detect structural cracks, leveraging a UHF chip equipped with tamper detection capability. This long reading distance inlay is glued to areas of concern on a concrete structure (i.e., areas suspected to be cracked or that may be extended in the near future). The inlays receive radio waves and the system can monitor the condition to avert disasters before they occur. DNP has developed the unique adhesive for the sheets that are attached to the concrete, which cures the agent via irradiation with ultraviolet rays (i.e., sunlight) or fluorescent light.
The new monitoring system can read all of the information collected by the inlay sheets at once via a UHF reader/writer, dramatically reducing inspection time, and the UHF range of Identiv’s tags allows for long communication distance. Small cracks are difficult to detect through visual inspection alone, and with Identiv’s technology, inspectors without special skills can make an accurate assessment, saving time and money, and potentially saving lives. The data collected is then transferred to local PCs for a full inspection report.
DNP’s infrastructure-monitoring system is scheduled to debut in Japan in March 2018.
