“…The LVDT offers infinite resolution, and its main advantages compared to similar sensors are its frictionless measurement, infinite mechanical life, high degree of robustness, excellent resolution, and good repeatability. 28,29 A wireless LVDT prototype was developed, implemented, and tested alongside a similar wired sensor in Veilleux et al 30 An experiment was performed in WiSe-Net lab at the University of Maine and at NASA Marshall Space Flight Center (NASA MSFC) using an RDP D2/200a LVDT to compare operational performance of both wireless and wired system. Experimental results demonstrated that the proposed wireless displacement prototype can be a promising replacement for current wired sensors by providing a similar performance while maintaining reliability and accuracy.…”

The importance of wireless sensor networks in structural health monitoring is unceasingly growing, because of the increasing demand for both safety and security in the cities. The speedy growth of wireless technologies has considerably developed the progress of structural monitoring systems with the combination of wireless sensor network technology. Wireless sensor network–based structural health monitoring system introduces a novel technology with compelling advantages in comparison to traditional wired system, which has the benefits of reducing installation and maintenance costs of structural health monitoring systems. However, structural health monitoring has brought an additional complex challenges in network design to wireless sensor networks. This article presents a contemporary review of collective experience the researchers have gained from the application of wireless sensor networks for structural health monitoring. Technologies of wired and wireless sensor systems are investigated along with wireless sensor node architecture, functionality, communication technologies, and its popular operating systems. Then, comprehensive summaries for the state-of-the-art academic and commercial wireless platform technologies used in laboratory testbeds and field test deployments for structural health monitoring applications are reviewed and tabulated. Following that, classification taxonomy of the key challenges associated with wireless sensor networks for structural health monitoring to assist the researchers in understanding the obstacles and the suitability of implementing wireless technology for structural health monitoring applications are deeply discussed with available research efforts in order to overcome these challenges. Finally, open research issues in wireless sensor networks for structural health monitoring are explored.

“…Several parameters need to be detected for bridge health, including strain, acceleration, displacement, temperature, and inclination [ 5 ]. For what concerns the displacement, contact sensors such as linear voltage differential transformers [ 6 ], ultrasonic sensors [ 7 , 8 ], ultrawideband (UWB) sensors [ 9 ], and accelerometers [ 10 , 11 , 12 ] provide high accuracy and are light and easy to maintain. However, their main limitation comes out when areas with difficult access have to be monitored.…”

Interferometric radars are widely used for monitoring civil structures. Bridges are critical structures that need to be constantly monitored for the safety of the users. In this work, a frequency-modulated continuous wave (FMCW) multiple-input multiple-output (MIMO) radar was used for monitoring an arched bridge in Catanzaro, Italy. Two measurements were carried out; a first standard measurement was made in a monostatic configuration, while a subsequent measurement was carried out in a multimonostatic configuration in order to retrieve the components of the deck displacement. A method that is able to predict the measurement uncertainty as a function of the multimonostatic geometry is provided, thereby aiming to facilitate the operators in the choice of the proper experimental setup. The multimonostatic measurement revealed a displacement along the horizontal direction that was four times higher than the one along the vertical direction, while the values reported in the literature correspond to a ratio of at most around 0.2. This is the first time that such a large ratio detected by radar has been reported; at any rate, it is compatible with the arched structure of this specific bridge. This case study highlights the importance of techniques that are able to retrieve at least two components of the displacement.
