“…Interest in the concept of self-monitoring structural components has grown in recent years due to its potential to enable continuous monitoring of the next generation of smart structures [91][92][93][94][95][96][97][98][99][100][101][102][103][104]. Considering the studies developed, the applications of piezoelectric embedded sensors for composite components are mainly based on structures or components of reinforced concrete [91,96,[98][99][100][101][102].…”

Sensing Technology (ST) plays a key role in Structural Health Monitoring (SHM) systems. ST focuses on developing sensors, sensory systems or smart materials that monitor a wide variety of materials properties aiming to create smart structures and smart materials, using Embedded Sensors (ESs), and allowing continuous and permanent measurements of the structural integrity. The integration of ESs is limited to the processing technology to embed the sensor due to its high-temperature sensitivity and the possibility of damage during its insertion into the structure. In addition, the technological process selection is dependent on the base material composition, either metallic or composite parts. The selection of smart sensors or the technology underlying them is fundamental to the monitoring mode. This paper presents a critical review of the fundaments and applications of sensing technologies for SHM employing ESs, focusing on the actual developments and innovation of these, as well as analysing the challenges that these technologies present, to build a path that allows a connected world through distributed measurement systems.

This paper proposes the use of a 1-dimensional (1-D) electromechanical impedance model to extract proper design guidelines when selecting patch-size and frequency range for corrosion detection in reinforced concrete structures using the electromechanical impedance (EMI) technique. The theoretical results show that the sensitivity mainly lies in the peak frequencies of the impedance spectrum, while outside resonant frequencies the sensitivity levels are low, and are prone to natural variation. If the mechanical impedance ratio between the host structure and patch is too large, the peaks and thereby the sensitivity decreases. This can be counteracted by increasing the patch thickness. Tests were carried out in reinforced concrete structures, where lead zirconate titanate (PZT) patches were attached to the rebars. Patches measuring 10 × 10 mm in length and width, with thicknesses of 0.3, 0.5 and 1.5 mm, were used. The results show that only the 10 × 10 × 1.5 mm patch, was able to generate a clear peak in the 50 kHz to 400 kHz impedance spectrum. Furthermore, a reinforced concrete structure with the 1.5 mm patch attached was induced significant corrosion damages, resulting in cracking of the structure. Due to this, a leftward shift of the main peak, and creation of new peaks in the spectrum was observed.

“…The fact that the changes in the structure could not be detected visually, the destructive test methods are not real-time and causes damage to the structure, the need for specialists and special equipment for detection of changes occurred in a construction directed the researchers to find new methods. One of these methods is the health monitoring of the building through the sensors embedded in the concrete structures [3][4][5][6][7][8].…”

In this study, a dipole antenna is designed for real-time damage assessment, humidity, and temperature monitoring in reinforced and non-reinforced concrete structures. The antenna-based sensor is embedded into reinforced and non-reinforced concrete beams to assess electromagnetic measurements. Reflection parameter S11 in dB values and resonant frequencies of the embedded antenna are evaluated to detect damage, humidity, and temperature changes. The exploratory results show that as deformation increases in reinforced concrete, resonance frequency values decrease and S11 values increase. The load and resonance frequency values showed very close trends as deformation increases in the beam. In water content sensing experiments, the S11 in dB values of the antenna decrease as the humidity increases for concrete specimens while the resonance frequency values increase as the humidity increases for the reinforced concrete specimen. Elevated temperature sensing experimental results show that the resonance frequency values of the antenna decrease as the temperature of the specimen increases for concrete specimens while the S11 in dB values increase as the temperature of the specimen increases for reinforced concrete specimen.
