Summary
This systematic literature review compares wireless sensor network (WSN) platforms and energy harvesting (EH) techniques for structural health monitoring (SHM) in bridges. It provides a comparative analysis to aid stakeholders in selecting optimal WSN and EH solutions for bridge SHM.
Area of Science:
- Engineering
- Computer Science
- Materials Science
Background:
- Structural Health Monitoring (SHM) is crucial for assessing infrastructure integrity, often utilizing Wireless Sensor Network (WSN) platforms.
- WSN platforms typically rely on batteries, posing limitations due to finite power and lifespan.
- Energy Harvesting (EH) technologies are increasingly integrated to overcome power constraints in WSNs for SHM.
Purpose of the Study:
- To conduct a systematic literature review (SLR) on WSN platforms and EH techniques for SHM in bridges.
- To provide an in-depth comparative analysis of various WSN platforms and EH techniques.
- To explore design considerations including sensor types, inspection scale, and response types within SHM systems.
Main Methods:
- A systematic literature review was performed, selecting 46 relevant articles published between 2007 and 2023.
- Articles were categorized into three groups: WSN platforms, EH techniques, and combined WSN-EH systems.
- A comparative analysis was conducted on the selected WSN platforms and EH techniques, alongside an exploration of sensor types, inspection scale, and response types.
Main Results:
- The review identified and classified numerous WSN platforms and EH techniques applicable to bridge SHM.
- A comparative analysis highlighted the strengths and weaknesses of different WSN platforms and EH techniques under various operating conditions.
- Seventeen distinct sensor types were identified across the reviewed literature, alongside an analysis of global/local inspection scales and static/dynamic response types.
Conclusions:
- This SLR offers a comprehensive overview and comparative analysis of WSN platforms and EH techniques for bridge SHM.
- The findings can significantly assist stakeholders in making informed decisions regarding the selection of appropriate WSN platforms, EH techniques, and related design parameters.
- The research addresses a gap in the literature by providing a systematic, in-depth comparison crucial for advancing SHM systems in bridges.

The utilization of strain gauges as transducers for converting mechanical strain into electrical signals is a common practice in various engineering applications. These strain gauges are frequently integrated into Wheatstone bridge circuits to accurately measure parameters such as force or pressure. Within this context, each element within the circuit exhibits a resistance that undergoes subtle variations when subjected to mechanical strain. The primary objective is to convert minuscule...

The analysis of suspension bridges is a complex and critical process that involves multiple factors, including the shape and tension of the main cables. The main cables of suspension bridges are subjected to distributed loads, which result in changes in tensile forces and deformation of the cable. These loads must be carefully considered to ensure that the bridge is safe and capable of supporting the weight of different loads.

An ohmmeter is a resistance-measuring device. It works by applying a voltage to a resistor of unknown resistance and measuring the current across the resistor. The resistance value is deduced using Ohm's law. Usually, the standard configuration of an ohmmeter comprises a voltmeter or an ammeter. However, such configurations are limited in accuracy because the meters alter the voltage applied to the resistor and the current that flows through it.
Thus, for accurate resistance measurements, a...

Indeterminate structures refer to structures where internal forces and reactions cannot be determined using only the equations of static equilibrium. Indeterminate structures have more unknown forces and reaction forces than equations of static equilibrium that can be used to determine them. Indeterminate structures are often used in engineering to create complex, efficient, and aesthetically pleasing structures. There are various types of indeterminate structures used in engineering and...
