Special Issue Information

Dear Colleagues,

The field of structural health monitoring (SHM) has become of great importance to investigate and maintain ocean structures (e.g., off-shore platforms, undersea tunnels, and submerged floating tunnels) as well as land structures (e.g., buildings and bridges). Sensors are crucial elements for providing reliable information on the health condition and performance of the structures as the ‘ears’ and ‘eyes’ of SHM. In particular, through sensors combined with sensor networks in underwater and terrestrial environments, the continuous monitoring of the structures has been performed, ensuring their safety. Moreover, by means of Internet of Things (IoT) technology, sensors and processors applied with the structures can communicate with each other, collaborating with unmanned underwater vehicles (UUVs) and unmanned aerial vehicles (UAVs), which lead to imagine them being ‘smart’. As a result, in order to assist the decision-making process regarding health monitoring, SHM with smart sensors will be increasingly used in real-life settings. SHM involves sensing and data analysis by means of AI and Big Data, and thus, its effectiveness depends on the technological advances in these fields.

The aim of this Special Issue is to bring together innovative developments in areas related to smart sensors in structural health monitoring, including but not limited to the following:

  • Novel sensors and sensing technologies;
  • Intelligent signal processing;
  • Smart operation strategies for sensor networks;
  • Innovative underwater and terrestrial sensor networks;
  • Adaptive monitoring;
  • Communication (security, resilience, low power, and low cost);
  • Data processing (distributed, aggregation, and big data);
  • Deployment (low cost, error prevention, and localization);
  • Remote monitoring in ocean and land structures;  
  • Collaboration with UUVs and UAVs.

Both review articles and original research papers covering smart sensors in structural health monitoring are solicited. In particular, papers with advances towards practical experiences and services are of interest.

This paper focuses on new instrumented trolleys, allowing automated 3D inspection of railway infrastructures, using optical scanning principles and devices for defects and damage evaluation. Inspection of rolling components is crucial for wear evaluation and to schedule maintenance interventions to assure safety. Currently, inspection trolleys are mainly instrumented with 2D contact or optical sensors. The application of 3D non-contact digitizers proposed in this paper allows for a quick and more complete monitoring of the health conditions of railways, also in combination with a proper procedure for automatic 3D inspection. The results of the experimental tests using 3D portable optical scanners on railways are compared with results obtained by a trolley instrumented with 2D contact sensors. The results demonstrate the effectiveness of the trolleys mounting 3D handheld optical digitizers with proper automated software inspection procedures. Full article
