“…Ultrasonic sensors emit an ultrasonic wave and measure the time it takes for the wave to reflect (the time of flight) after hitting an object [49]. Ultrasonic sensors have a range of applications, including distance measurement, level sensing, and object detection and avoidance in robotics [50].…”

“…AC impedance spectroscopy (ACIS) is a promising non-destructive technique that can study the microstructural composition of cement-based sensors. Many researchers have been recently used it and can provide valuable insights into the microstructural characterization of these sensors [47][48][49][50][51]. The fundamental concepts of piezoresistivity and ACIS include the piezoresistivity theory, resistance measurement methodology, strain/damage sensing, theories of conduction, the AC impedance spectroscopy theory, and equivalent circuit models [57][58][59].…”

Structural health monitoring (SHM) is crucial for maintaining concrete infrastructure. The data collected by these sensors are processed and analyzed using various analysis tools under different loadings and exposure to external conditions. Sensor-based investigation on concrete has been carried out for technologies used for designing structural health monitoring sensors. A Sensor-Infused Structural Analysis such as interfacial bond-slip model, corroded steel bar, fiber-optic sensors, carbon black and polypropylene fiber, concrete cracks, concrete carbonation, strain transfer model, and vibrational-based monitor. The compressive strength (CS) and split tensile strength (STS) values of the analyzed material fall within a range from 26 to 36 MPa and from 2 to 3 MPa, respectively. The material being studied has a range of flexural strength (FS) and density values that fall between 4.5 and 7 MPa and between 2250 and 2550 kg/m3. The average squared difference between the predicted and actual compressive strength values was found to be 4.405. With cement ratios of 0.3, 0.4, and 0.5, the shear strength value ranged from 4.4 to 5.6 MPa. The maximum shear strength was observed for a water–cement ratio of 0.4, with 5.5 MPa, followed by a water–cement ratio of 0.3, with 5 MPa. Optimizing the water–cement ratio achieves robust concrete (at 0.50), while a lower ratio may hinder strength (at 0.30). PZT sensors and stress-wave measurements aid in the precise structural monitoring, enhanced by steel fibers and carbon black, for improved sensitivity and mechanical properties. These findings incorporate a wide range of applications, including crack detection; strain and deformation analysis; and monitoring of temperature, moisture, and corrosion. This review pioneers sensor technology for concrete monitoring (Goal 9), urban safety (Goal 11), climate resilience (Goal 13), coastal preservation (Goal 14), and habitat protection (Goal 15) of the United Nations’ Sustainable Development Goals.

“…Fixed point non-destructive testing is suitable for spot checks and cannot accurately locate the amount or location of corrosion damage. In response to the above issues, this project is based on ultrasonic sensing technology to design a fully covered non-destructive testing system for oil production pipelines (Aleshin et al, 2022;Kim et al, 2023). It can not only achieve regular and comprehensive detection of pipeline inner wall damage or corrosion, but also achieve efficient and automated operation, solving problems such as missed inspections and inaccurate damage positioning (Ang et al, 2023).…”

A design of a non-destructive testing system for underwater pipelines based on ultrasound has been proposed, consisting of a three-axis control system and an ultrasonic thickness measurement system. This can achieve full coverage testing and real-time data transmission of pipeline wall thickness through integrated composite rotating mechanisms, travel driving mechanisms, pipeline surface preprocessing mechanisms, data acquisition systems, etc., with high automation and the ability to achieve pipeline based testing. Among them, the pipeline surface pretreatment mechanism includes a polishing mechanism and a circulating immersion system, which are used to improve the coupling effect between the pipeline wall and the ultrasonic probe. This non-destructive testing system can achieve high detection efficiency and testing accuracy, effectively solving the current problems of undersea pipeline leakage and inaccurate positioning of corrosion damage. At present, the problem of global and efficient scanning still needs to be solved, as otherwise it will be difficult to further improve work efficiency. Highlights A design of a non-destructive testing system for underwater pipelines based on ultrasound has been proposed, consisting of a three-axis control system and an ultrasonic thickness measurement system The system can realize scanning detection with high efficiency and automation The system is equipped with an automatic coupling mechanism to ensure the stability and reliability of the work
