The electrostrictive effects in anisotropic tissue, such as muscle, are interesting and qualitatively different than in an isotropic material. A striking feature in anisotropic tissue is the presence of a charge distribution, which is absent in isotropic tissue. This charge interacts with the electric field to give rise to body forces that deform the tissue. We develop an electromechanical model to investigate how anisotropic tissue deforms due to an electric field, and find analytical solutions for the pressure and displacement. The distribution of the pressure and displacement are complex and dependent on the boundary conditions. The effects of electrostriction are small, but comparable in size to pressures and displacements in other imaging modalities that utilize similar mechanical effects.
