Catastrophic Thinning of Dielectric Elastomers [PDF]

open access: yesPhysical Review Letters, 2017
We provide an energetic insight into the catastrophic nature of thinning instability in soft electroactive elastomers. This phenomenon is a major obstacle to the development of giant actuators, yet it is neither completely understood nor modeled accurately.
