Giant voltage-induced deformation in dielectric elastomers near the verge of snap-through instability

     Dielectric elastomers are capable of large voltage-induced deformation, but achieving
such large deformation in practice has been a major challenge due to electromechanical
instability and electric breakdown. The complex nonlinear behavior suggests an important
opportunity: electromechanical instability can be harnessed to achieve giant voltage-induced
deformation.
