Real-time durability monitoring systems in large building structures are an essential technology for smart cities. In this study, a smart structural-durability health-monitoring (SDHM) system is designed and demonstrated. The SDHM system consists of embedded multisensing sensors, data processing modules, and a subwavelength wideband antenna operating at 900 MHz. The sensors reversibly examine the degradation factors inside the concrete, possibly offering real-time depth profiles. A subwavelength wideband antenna ensures stable transmission performance regardless of the corrosive concrete conditions with minimal perturbation. Moreover, a user interface was developed for a six-channel real-time SDHM. Therefore, SDHM integrating each component could diagnose the corrosion levels at early stages, which is highly suitable for ubiquitous city infrastructures.
