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 ...

Granularly Coupled Dielectric Elastomer Actuators
IEEE/ASME Transactions on Mechatronics, 2011 Dielectric elastomer actuators (DEAs) have been demonstrated to represent today a high-performance technology for electroactive polymer mechatronics. As a means to improve versatility and safety of DEAs, so-called “hydrostatically coupled” DEAs (HC-DEAs) have recently been shown to offer new opportunities.

Simulation of Networked Dielectric Elastomer Balloon Actuators
IEEE Robotics and Automation Letters, 2016 A dielectric elastomer is able to act as an actuator when subjected to an electric field. However, the allowable deformation of dielectric elastomer actuators is severely limited by the material failures. To extend the actuation range, this letter investigates a network of two interconnected dielectric elastomer balloon actuators, each prestretched by ...

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 ...

Wireless Powered Dielectric Elastomer Actuator [PDF]
IEEE Robotics and Automation Letters, 2021 The need for cable connection with soft robotic systems suppresses the benefits granted by their softness and flexibility. Such systems can be untethered by equipping batteries or by relying on non-electrical actuation mechanisms. However, these approaches cannot simultaneously support long-term and intelligent operations.
