Converse electrostrictive effect in dielectric polymers
Résumé
This paper aims at exposing a physical model for converse dielectric electrostrictive effect using Debye/Langevin formalism through the use of Boltzmann's statistics. The principle of the proposed approach consists of considering the electric field orientability of dipoles within the polymer matrix as a function of the applied strain, allowing the derivation of the polarization or electric displacement as a function of the electric field and strain or stress. The proposed model also permits taking into account the saturation effect that occurs in the polarization and that limits the mechanical to electrical conversion in electrostrictive dielectric polymers. © 2013 Elsevier B.V.
