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.

“…(7) Previous studies have described the magnetic memory time. (8)(9)(10) Higashitani et al investigated the effects of magnetic exposure on the zeta potential and diffusivity of polystyrene latex particles. It was found that magnetic exposure decreased the zeta potential and the magnetic effect remained for at least six days.…”

To investigate the effects of magnetic induction intensity, magnetic field treatment time, and solution concentration on the magnetic memory time of CaCO 3 solution, an orthogonal experiment was carried out to establish a L 16 (4 5) orthogonal table, and 16 groups of experimental results were obtained on the basis of a self-made electromagnetic water treatment experimental platform. Range and variance analyses were carried out. Experimental results indicated that the main factor affecting the magnetic memory time of CaCO 3 solution is the magnetic induction intensity and the effect is significant. The magnetic field treatment time and solution concentration have little effect on the magnetic memory time. In addition, optimum experimental conditions were obtained. When a CaCO 3 solution of 2 mmol/L concentration was treated for 36 h with a magnetic induction intensity of 300 Gs, the longest magnetic memory time (about 5600 min) was observed. These research results provide the theoretical basis for the selection of subsequent experimental parameters.

“…The magnetic field mainly acts through the CO 3 −2 in the solution to produce small particles; in addition, the proportion of the aragonite crystals is high, and these crystals easily flow with the liquid rather than adhere to the tube wall . When the magnetic field disappears, the magnetized solution cannot immediately be restored to its original state due to the magnetic memory effect; this period is called the magnetic memory time . The magnetic field affects the scale ions and the properties of water.…”

The absorbance values of specific configuration solutions under different magnetic treatment conditions are studied using the UV method based on the circulating dynamic simulation experiment platform for the anti‐scaling of electromagnetics. Additionally, the relationship between the absorbance value and solution concentration is determined. Moreover, the nucleation rate of CaCO3 is calculated using the absorbance value. The influence of the specific magnetic field on nucleating rate is analyzed. Subsequently, the magnetic memory effect and time of CO3−2 and water are studied. Results show that the magnetic treatment changes the nucleation rate of CaCO3 and the critical oversaturation of the solution by acting on CO3−2. This treatment also can promote the dissolution of CaCO3 in water by changing the properties of water. These two aspects all exert memory effects; however, their respective memory times are different. Moreover, the results show that the magnetic treatment can reduce the critical oversaturation of the CaCO3 solution and accelerate the nucleation rate. Furthermore, the memory time of the magnetic field acting on CO3−2 and the properties of water are 45 min and 78 h, respectively.
