The growing demand towards life cycle sustainability has created a tremendous interest in non-destructive evaluation (NDE) to minimize manufacturing defects and waste, and to improve maintenance and extend service life. Applications of Magnetic Sensors (MSs) in NDE of civil engineering structures have become of great interest in recent years due to their non-contact data collection, and their high sensitivity under the influence of external stimuli such as strain, temperature, and humidity, to detect damage and deficiencies. There have been several advancements in MSs over the years for strain evaluation, corrosion monitoring, etc. based on the magnetic property changes. However, these MSs are at their nascent stages of development, and thus, there are several challenges that exist. This paper summarizes the recent advancements in MSs and their applications in civil engineering. Principle functions of different MSs are discussed, and their comparative characteristics are presented. The research challenges are highlighted and the roadmap towards high technology readiness level is discussed.

“…Embedded inductive sensors have been developed to monitor the corrosion of internal steel rebar [7], but this technique requires an applied electric current, and only shows the average corrosion between two points. Additional work on monitoring steel corrosion has proven magnetic sensing a viable method of non-destructive evaluation of similar structures, with obtained magnetic signals shown to be significantly strong as compared the background noise present in the system [8]. That work also proposed Giant Magneto-Resistive (GMR) sensors, which measure magnetic field strength, as a possible magnetic sensor for non-destructive evaluation of internal steel bars due to low power consumption and a wide sensing range.…”

In the field of structural health monitoring (SHM), innovative methods of non-destructive evaluation (NDE) are currently being investigated with the purpose of providing prognostic information toward safer, longer lasting structures. Therefore, it is desirable to integrate NDE techniques with existing structural reinforcement techniques for in situ measurement capability, increasing service life. Magnetic shape memory alloys (MSMAs) offer the potential for NDE via magnetic sensing, while further offering the multi-functionality of crack closing and structural reinforcement. The current research proposes a novel SHM approach for concrete structures using embedded MSMAs for magnetic sensing, and investigates the properties of such a system.
