“…A group of specimens with different Au NPs concentrations were cured and subjected to an external electric field ( ) to increase the cement paste's inherent piezoelectric response [ 11 , 12 ]. The electric field was produced by two copper plane electrodes of sides 13 cm and 10 cm, which were oriented to pointing in the axial direction of the cylinders, using a DC source at 20.5 V throughout the curing time (28 days).…”

“…The constant can be multiplied by the factor A/L (A is the cross-section, and L is the distance between electrodes) to obtain the piezoelectric voltage parameter g 33 (generally presented in units of mVm/N), as demonstrated Al-Qaralleh [ 14 ] for blended cement pastes cured under an external electric field and validated going forward by Triana-Camacho et al. for graphene oxide-cement composites [ 12 ]. For instance, in Fig.…”

“…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].…”

“…Resonance method within which a piezoelectric sample is clamped at its edges and driven into resonance using an ac voltage source [14]. Differential capacitance method involves measuring the change in capacitance of a piezoelectric sample as it is subjected to mechanical stress [15]. Laser Interferometry techniques can be used to measure the displacement or strain induced in a piezoelectric material when subjected to an electric field [16].…”
