“…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]. The development of structures or components of reinforced concrete, with PSs, incorporated to obtain smart structures is particularly suitable to be implemented in numerous strands, mainly in civil engineering, because PSs are characterized by being reliable and stable in the long term.…”

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.

“…Nowadays, elucidating the mechanical properties of concrete structures under dynamic loads has become one of the research hotspots in the civil engineering field [4,5]. Meanwhile, it has become a trend to rely on intelligent systems to implement health monitoring and damage forecasting methods for these structures [6][7][8]; however, it is difficult to practically apply these approaches [5][6][7]. Current piezoelectric smart materials exhibit several shortcomings, such as high costs, poor compatibility, and poor durability, which limit their applicability [5,[8][9][10].…”

“…Because of their low costs, fast response speeds, good reliability, suitable linear relationship, and decent electro-mechanical response characteristics, they also can be used in sensors and actuators [15][16][17][18]. In recent years, the good matching performance of cement-based piezoelectric composite materials and concrete materials has led to the development of a multifunctional sensor suitable for civil engineering [8,11,19]. Compared with traditional piezoelectric materials, this novel sensor has two outstanding advantages: good performance and designability, and better compatibility with the concrete structure [20].…”

By employing ordinary Portland cement as a matrix and PZT-5H piezoelectric ceramic as the functional body, 1-3 and 2-2 cement-based piezoelectric composites were prepared. Quasi-static compression tests were performed along with dynamic impact loading tests to study the electro-mechanical response characteristics of 1-3 and 2-2 cement-based piezoelectric composites. The research results show that both composites exhibit strain rate effects under quasi-static compression and dynamic impact loading since they are strain-rate sensitive materials. The sensitivity of the two composites has a non-linear mutation point: in the quasi-static state, the sensitivity of 1-3 and 2-2 composites is 157 and 169 pC/N, respectively; in the dynamic state, the respective sensitivity is 323 and 296 pC/N. Although the sensitivity difference is not significant, the linear range of the 2-2 composite is 24.8% and 61.3% larger than that of the 1-3 composite under quasi-static compression and dynamic impact loading, respectively. Accordingly, the 2-2 composite exhibits certain advantages as a sensor material, irrespective of whether it is subjected to quasi-static or dynamic loading.

With the advent of the intelligence era, flexible piezoelectric tactile sensors are the key components for sensing information and sending signals. The performance parameters of piezoelectric sensors are closely related to the selection of piezoelectric materials. Compared with conventional piezoelectric materials, polyvinylidene fluoride (PVDF) has significant advantages in flexibility, stretchability, chemical stability, electromechanical conversion, ease of use, and acoustic propagation impedance. As a result, PVDF has become a popular topic of research. This paper introduces the working principle of piezoelectric materials and flexible piezoelectric sensors based on PVDF materials and details the research progress of different materials based on PVDF for the preparation of flexible piezoelectric tactile sensors, such as: PVDF and its copolymers for the preparation of flexible piezoelectric sensors and PVDF doped with other functional materials for the preparation of flexible piezoelectric sensors. In this paper, the advantages and disadvantages of different materials and the development prospects of PVDF flexible piezoelectric sensors are summarized to provide some insights for high‐performance flexible PVDF piezoelectric sensors.
