Polyvinyl chloride-based dielectric elastomer with high permittivity and low viscoelasticity for actuation and sensing [PDF]
Nature Communications, 2023 Dielectric elastomers (DEs) are widely used in soft actuators but existing DE actuators often require high driving electrical fields. Here the authors demonstrate that introducing cyanoethyl cellulose into plasticized PVC gel confers high dielectric ...

Dielectric elastomer actuators [PDF]
Journal of Applied Physics, 2021 Dielectric elastomer actuators (DEAs) are soft, electrically powered actuators that have no discrete moving parts, yet can exhibit large strains (10%–50%) and moderate stress (∼100 kPa). This Tutorial describes the physical basis underlying the operation of DEA's, starting with a simple linear analysis, followed by nonlinear Newtonian and energy ...

International Journal of Engineering and Advanced Technology, 2021 This paper appraisals state-of-the-art dielectric elastomer actuators (DEAs) and their forthcoming standpoints as soft actuators which have freshly been considered as a crucial power generation module for soft robots. DEs behave as yielding capacitors, expanding in area and attenuation in thickness when a voltage is applied.

Catastrophic Thinning of Dielectric Elastomers [PDF]
Physical 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.
