This study proposes a new model that couples the piezoelectric and electrostrictive behavior to minimize the polarization power of composite polymer. The development of this model is capable to predict the energy harvesting abilities of an electrostrictive composite. To improve the dielectric permittivity of electrostrictive polymer, the particles of PZT have been incorporated in order to increase the conversion efficiency of the composite. Dielectric characterization tests showed an increase in dielectric permittivity by a factor of 4.5 compared to pure polymer. Experimental measurements of harvested power validate the analytical model and demonstrate a good correlation between the two data. An equivalent of an electrical scheme has been developed, which allows modeling the two behaviors. The harvested power density under low frequency at 2% of strain can reach 0.30 μW/cm 3 for 33% of PZT without the polarization field, including the conversion efficiency becomes higher. The energy harvester property of this material composite has excellent potential for several selfpowered applications such as wireless sensor networks and the internet of things.

“…We note that our electrostrictive polymer was subjected to a dc‐biased electric field. Because the polymer was not piezoelectric, it was necessary to induce polarization with a dc bias to obtain pseudo‐piezoelectric behavior . The configuration of a schematic of the sample was under investigation in this study is illustrated in Fig.…”

“…In the setup developed for characterizing the power harvested, the electrostrictive polymer was subjected to a dc biased electric field, produced by a generator function and amplified by a high‐voltage power amplifier. The film was stretched with different strain amplitudes of 2%, 4% and 6.5% at f e = 3 Hz and f m = 6 Hz.…”

“…Electrostrictive polymers are a novel class of electro‐active polymers (EAPs) that recently became the object of considerable research efforts because of their actuation properties . The newest studies demonstrate the possibility of harvesting mechanical energy using these particular materials . In general, EAPs exhibit significant advantages compared to piezoelectric ceramics; they are lightweight, flexible and low‐cost and have a good processability and low mechanical impedance.…”

In the field of vibrational energy harvesting, the electromechanical conversion demonstrated the many advantages of using electrostrictive polymers. These materials present advantageous features such as high productivity and high flexibility. The aim of this work is to provide a solution for artificially increasing the current flowing through the sample when simultaneously driven by an electrical field and a mechanical excitation in order to determine the optimal range of deformation for a good efficiency of the electromechanical conversion. Thus, by using the fast Fourier transform (FFT) analysis, our experimental results, shown clearly that under certain conditions of strain S (Si4 %), the efficiency of energy harvesting becomes significant, indicating that the mechanical parameter S was a crucial parameter for a better efficiency of electromechanical conversion. Furthermore, a good agreement between theoretical and experimental results was found.

“…There are also several research works on their use for energy harvesting [1][2][3][4]. Currently, the most used piezoelectric materials are ceramics and most of these ceramics are lead-based (PZT, PMN-PT …) because of the high properties (density, d33, k33, Qm) attributed to the presence of lead in the structure of these ceramics.…”

The Barium Titanates are very promising materials ecologically, but still have poor piezoelectric properties compared to the Lead Zirconate Titanates. So in order to improve them, a substitution of the zirconium in our ceramic (BT) has been investigated by X-ray diffraction (XRD) and grain size distribution. After the preparation of the BZT powder in chemical way we have added a sintering aid (Li 2 O 3 -Bi 2 O 3 -CuO) and we have tried to study our massive ceramic. The X-ray diffraction, grain size distribution and scanning electron microscope of the BZT with LBCu show a better particles arrangement and density. In other hand we have noticed an important improvement of the piezoelectric properties (d 33 = 220 pC/N at 25°C) especially in comparison with other lead-free ceramics. These properties make BZT a lead-free high performance material for piezoelectric applications.
