A Robotic Testing Platform for Pipelined Discovery of Resilient Dielectric Elastomer Actuators. [PDF]
Adv Sci (Weinh)This work introduces a robotic testing platform enabling high‐throughput, multi‐parameter lifetime mapping of linear dielectric elastomer actuators (DEAs). By integrating programmable high‐voltage control and automated electromechanical measurements, the system identifies material and operating conditions that double actuator lifetime.

Effect of Prestrain on the Actuation Characteristics of Dielectric Elastomers [PDF]
Polymers, 2020 Dielectric elastomers (DEs) represent a class of electroactive polymers that deform due to electrostatic attraction between oppositely charged electrodes under a varying electric field. Over the last couple of decades, DEs have garnered considerable attention due to their much-coveted actuation properties.

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.

Actuation response of polyacrylate dielectric elastomers [PDF]
SPIE Proceedings, 2001 Polyacrylate dielectric elastomers have yielded extremely large strain and elastic energy density suggesting that they are useful for many actuator applications. A thorough understanding of the physics underlying the mechanism of the observed response to an electric field can help develop improved actuators.

Dielectric elastomer actuator biased by magnetorheological elastomer with permanent magnet
Smart Materials and Structures, 2023 Abstract Dielectric elastomer actuators have become one of the most important smart material transducers in recent times. One of the crucial aspects in this field is the application of bias to find the best operating conditions. The basic task is to find the proper bias configuration to obtain a wide range of displacements in the ...
