“…Furthermore, piezoelectric properties extend beyond energy harvesting; these composites can generate energy without relying on external power sources to detect electric responses resulting from strain measurements, as observed in piezoresistive cement-based composites [8,9]. In other words, these nanocomposites have the ability to produce a small amount of voltage, electrical current, or power in response to applied strain, as demonstrated by Triana-Camacho et al in their study on reduced graphene oxide-cement composites [10]. They also suggested that electric power could be a great candidate as a sensing parameter in real SHM applications.…”

“…The coefficient g 33 reveals how much electrical charge can polarize and generate a voltage in the cement-based composite, while d 33 shows how long it can preserve such polarization. In that sense, energy harvesting depends on both characteristics described above, which can be modified with different dispersion methodologies [10] or using different concentrations of the nanocomposite with respect to the cement mass [11]. Hence, the inherent self-sensing capabilities of piezoelectric cement-based composites can be effectively utilized in civil structures, including bridges [12], obviating the need for intricate monitoring systems or external transducers [13].…”

Piezoelectric cement-based composites could serve to monitor the strain state of structural elements or act as self-powered materials in structural health monitoring (SHM) applications. The incorporation of piezoelectric materials as an active phase within cement matrices has presented a highly attractive avenue until today. However, their application is challenged by the low electrical conductivity of the hydrated cement matrix. Gold nanoparticles (Au NPs) possess substantial potential for elevating the free electrical charge within the matrix, increasing its electrical conductivity between the Au NPs and the cement matrix, thereby enhancing the piezoelectric response of the composite. In this sense, the objective of this study is to investigate the effects of incorporating low concentrations of gold nanoparticles (Au NPs) (442 and 658 ppm) on the electrical and piezoelectric properties of cement-based composites. Additionally, this study considers the effects of such properties when the material is cured under a constant electric field. Electrical impedance spectroscopy was used to evaluate the polarization resistance and piezoresistive properties of the material. Additionally, open-circuit potential measurements were taken alongside the application of mechanical loads to assess the piezoelectric activity of the composites. The findings revealed a notable decrease in the composite’s total electrical resistance, reaching a value of 1.5 ± 0.2 kΩ, almost four times lower than the reference specimens. In the realm of piezoelectricity, the piezoelectric voltage parameter g33 exhibited a remarkable advancement, improving by a factor of 57 when compared to reference specimens. This significant enhancement can be attributed to both the concentration of Au NPs and the electrical curing process. In summary, the outcomes of this study underscore the feasibility of creating a highly electrically conductive cement-based matrix, using low concentrations of gold nanoparticles as electric charge carries, and indicate the possible piezoelectric behavior of the studied compposite.

Characterizing piezoelectric coefficients d33 and d31 is crucial in diverse applications. Here, an extensive analysis of the correlation between d33 and d31 in piezoelectric materials, employing strain relationships is presented. Utilizing the fundamental principles of stress and volume conservation, in conjunction with a capacitance voltage profile, d33 is extracted in terms of measured capacitance and the applied bias. This methodology promises advancements in piezoelectric material understanding and engineering across various technological applications. The experimental framework utilized PZT thin film piezoelectric materials of 300 nm thickness with predetermined d33 value of 200 pm/Volts, where measurements were carried out to monitor changes in capacitance under varying poling conditions. This method effectively led to the determination of the d33 coefficient, which was approximately measured at 208 pm/Volt. This approach offers a rapid and efficient method for estimating piezoelectric coefficients, promising advancements in the characterization and application of piezoelectric materials.INDEX TERMS Characterizations, electrical capacitance, piezoelectric coefficient, PZT, strain.
