“…In addition to distributed FOSs, resistance wire strain gauges and flash thermography were used to assess the joint during quasi-static loading conditions. In [ 361 ], Li et al examined different parameters, such as coating type and twist prestress, to improve the measurement sensitivity of distributed FOS in Rayleigh-Backscattering sensing (ODiSI-B by Luna Innovations) under aircraft operational and environmental conditions. Recently, an optical fiber grating temperature sensor inserted inside a lithium-ion Hardcase battery was proposed by Wu et al [ 362 ] for long-term in situ temperature measurements.…”

This paper reviews recent advances in sensor technologies for non-destructive testing (NDT) and structural health monitoring (SHM) of civil structures. The article is motivated by the rapid developments in sensor technologies and data analytics leading to ever-advancing systems for assessing and monitoring structures. Conventional and advanced sensor technologies are systematically reviewed and evaluated in the context of providing input parameters for NDT and SHM systems and for their suitability to determine the health state of structures. The presented sensing technologies and monitoring systems are selected based on their capabilities, reliability, maturity, affordability, popularity, ease of use, resilience, and innovation. A significant focus is placed on evaluating the selected technologies and associated data analytics, highlighting limitations, advantages, and disadvantages. The paper presents sensing techniques such as fiber optics, laser vibrometry, acoustic emission, ultrasonics, thermography, drones, microelectromechanical systems (MEMS), magnetostrictive sensors, and next-generation technologies.
