Finite bending and pattern evolution of the associated instability for a dielectric elastomer slab [PDF]
, 2018 We investigate the finite bending and the associated bending instability of an incompressible dielectric slab subject to a combination of applied voltage and axial compression, using nonlinear electro-elasticity theory and its incremental version.

Circuit Electromechanics with a Non-Metallized Nanobeam
, 2014 We have realized a nano-electromechanical hybrid system consisting of a silicon nitride beam dielectrically coupled to a superconducting microwave resonator. We characterize the sample by making use of the Duffing nonlinearity of the strongly driven beam.
