Voltage-induced pitting pattern formations of constrained dielectric elastomer membranes

By: Lisa Lee, Baohong Chen, and Ehsan Hajiesmaili

Local instabilities have been observed when a large DC voltage is applied to a dielectric elastomer film, attached to a rigid and conducting substrate on one side and coated with a compliant electrode on the other side. Threshold voltage and wavelength of these local instabilities are analyzed in the following using the energy minimization method.
