Effect of Multilayer Dielectric Elastomer Actuator (DEA) Construction on Performance and Breakdown Strength

ASME 2022 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, 2022
Abstract Dielectric elastomer actuators (DEAs), unlike traditional actuators, are lightweight, soft, smart materials that are proving to be attractive in a broad range of potential applications such as robotic arms, artificial muscles, medical devices, stretchable sensors, grippers, loudspeakers, and automotive lightweighting.

Effect of electrode composition and patterning method on the lifetime of silicone-based dielectric elastomer actuators (DEA) under different environmental conditions

Electroactive Polymer Actuators and Devices (EAPAD) XXIII, 2021
We report an experimental investigation of the lifetime of dielectric elastomer actuators (DEAs) under constant DC actuation, with a characterization setup which allows the monitoring of strain and resistance over time for 6 DEAs in parallel. We show how the choice of the electrode influences the lifetime of silicone-based DEAs under constant DC ...

Partial discharge analysis of prestretched and unstretched acrylic elastomers for Dielectric Elastomer Actuators (DEA)

SPIE Proceedings, 2012
Partial discharges (PD) occur in solid insulating materials when the insulating material is partially bridged by an electrical discharge in response to an applied voltage stress. PDs typically occur at localized points of high field stresses or at voids and other inhomogeneities within the insulator.

A smart experimental technique for the optimization of dielectric elastomer actuator (DEA) systems

Smart Materials and Structures, 2015
In order to aid in moving dielectric elastomer actuator (DEA) technology from the laboratory into a commercial product DEA prototypes should be tested against a variety of loading conditions and eventually in the end user conditions. An experimental test setup to seamlessly perform mechanical characterization and loading of the DEA would be a great ...
