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.

“…The increase of the amount of filler generally leads to shorter chains in the polymeric network and, subsequently, to strain‐stiffening behavior; on the other side, experimental evidences show that an increase of filler particles plays a negative role on the insulating properties of the dielectric membrane, inducing a sensible reduction of the maximum electric field that can be sustained by the polymer . Also the role of thickness, prestretch and frequency were reported to play a role in the electrical behavior of the film . Notwithstanding, in this work we specifically confine all possible sources of nonlinearities and dissipation in the mechanical response of the polymeric film, we neglect constitutive electromechanical coupling and, regarding the electrical behavior, we adhere a well grounded experimental literature according to which EAPs can be considered linear dielectrics in a wide range of deformations—see for example Suo…”

Electroactive polymer energy harvesters are promising devices for the conversion of mechanical work to electrical energy. The performances of these devices are strongly dependent on the mechanical response of the polymeric material and on the type of electromechanical cycle, and these are limited by the occurrence of dielectric breakdown, compression induced wrinkling and electromechanical instability (pull-in). To identify the optimal electromechanical cycle that complies with all of these limitations, we set-up and solve a constraint optimization problem and we critically discuss the influence of material behavior of the polymer in the optimal performances of the energy harvesting device. Finally, we show that if the rate-independent dissipative behavior of the polymer (Mullins effect) is neglected, the optimization procedure may lead to quite unsatisfactory predictions: by making reference to explicit experimental data from literature we show that an optimal harvesting cycle deduced by neglecting the Mullins effect is far from being optimal when this is taken in consideration.
