“…As a result, they proved that cement-based piezoelectric ceramic sensors could be used to monitor crack propagation in real time. Im et al [23] developed an ultra-thin iron corrosion sensor covered with an anion exchange membrane to monitor the corrosion level of rebars within reinforced concrete effectively. In their study, they embedded the developed sensor at 10 mm intervals in mortar specimens.…”

Embedded sensors are widely employed for the structural health monitoring of structures constructed with concrete or mortar. Despite embedded sensors being actively used, there has been no study on whether or not the sensor probe placement within structures made of concrete or mortar influences their structural stability. The strength of small structures in particular could be affected by sensor probes embedded within them. To address the lack of research in this area, this study analyzed the effect of embedding positions of sensor probes on the compressive strength development of mortar. After the production of mortar specimens with the depth of the embedded sensor being controlled by the developed mold, compressive strength tests were conducted, and then test results were verified through finite element analysis. For testing, copper–nickel-plated sensor probes were embedded within the mortar because these sensor probes are popular commercial probes. The test results show that the compressive strength was 7.1 MPa when the sensor probe was embedded at a depth of 5 mm. In contrast, the compressive strength was 28.2 MPa at a depth of 30 mm. Since the compressive strength without the embedded sensor probe was 29.8 MPa, considering the results of this study, it is highly recommended that copper–nickel-plated sensor probes be embedded at least 30 mm from the surface of mortar structures.

Smart and functional materials processed by printing technologies reveal an increasing interest due to small cost assembly, easy integration into devices and the possibility to obtain multifunctional materials over flexible and large areas. After introducing smart materials, printing technologies and inks, this review discusses the materials that are already being printed, mainly piezoelectric, piezoresistive, magnetostrictive, shape memory polymers (SMP), pH sensitive and chromic system materials. Since polymer-based smart materials are particularly attractive for device implementation, this review will focus on printed polymer-based smart materials. Finally, critical challenges and future research directions will be addressed.

Composite structures and materials find widespread applications across industries such as civil engineering, automotive, and aerospace owing to their exceptional strength-to-weight ratio, stiffness, and resistance to corrosion. However, these materials are prone to various forms of damage, including matrix cracking, delamination, and fiber breakage, which can compromise their performance and lead to failure. Hence, the development of robust health monitoring and inspection (HMI) techniques is imperative for the multi-damage detection and durability assessment of composite structures and materials. Electromechanical impedance (EMI) emerges as a promising HMI technique for such applications. EMI, a non-destructive testing (NDT) method, involves measuring the electrical impedance of a piezoelectric sensor bonded to the structure, enabling detection and characterization of damage. In this study, standard cube specimens were cast using OPC cement, Class F fly ash, and polypropylene fiber mixture. Analysis revealed a direct correlation between the Root Mean Square Deviation (RMSD) index and crack dimensions, with heightened sensitivity observed at smaller patch-to-damage distances. Moreover, the conductance and susceptance signatures consistently shifted with increasing damage, with significant leftward shifts indicating damage severity. A new damage index, ranging from 0 to 1, facilitated quantitative damage analysis, exhibiting pronounced variation in the 30–400 kHz frequency range. Additionally, equivalent stiffness and damping structure parameters were evaluated. Overall, the research demonstrates the effectiveness of surface piezoelectric sensors based on the EMI technique in monitoring concrete damage and its evolution, providing valuable insights for predicting the service life and durability of concrete structures.
