Soft active materials have many important applications. We develop a theory of large deformation in a family
of soft active materials known as dielectric elastomers. We show that the Maxwell stress is not applicable to deformable
dielectrics in general, and that the effect of electric field on deformation is material specific. Based on available
experimental data, we construct for a class of model materials, which we call ideal dielectric elastomers, a free-energy
function comprising contributions from stretching and polarizing. We show that the free-energy function is typically
non-convex, causing the pull-in instability of dielectric elastomers.
