Modeling of a Dielectric Elastomer Bender Actuator
Actuators, 2014 The current smallest self-contained modular robot uses a shape memory alloy, which is inherently inefficient, slow and difficult to control. We present the design, fabrication and demonstration of a module based on dielectric elastomer actuation.

Effects of Thinner Compliant Electrodes on Self-Clearability of Dielectric Elastomer Actuators
Actuators, 2020 A metalized plastic capacitor stands a higher chance to clear faults when embodied with thinner electrodes. However, it is not clear whether the same thickness effect applies to carbon-based compliant electrodes in clearing the defects in dielectric ...

On rate-dependent dissipation effects in electro-elasticity [PDF]
, 2014 This paper deals with the mathematical modelling of large strain electro-viscoelastic deformations in electro-active polymers. Energy dissipation is assumed to occur due to mechanical viscoelasticity of the polymer as well as due to time-dependent ...

Soft, tough, and fast polyacrylate dielectric elastomer for non-magnetic motor
Nature Communications, 2021 Dielectric elastomer actuators (DEAs) with large electrically actuated strain can be used in non-magnetic motors, but high stiffness, poor strength and slow response currently limit the application of DEAs.
