Wireless Powered Dielectric Elastomer Actuator [PDF]

open access: yesIEEE 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.

Polyvinyl chloride-based dielectric elastomer with high permittivity and low viscoelasticity for actuation and sensing

open access: yesNature 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 ...

Theoretical study of the electroactive bistable actuator and regulation methods

open access: yesInternational Journal of Smart and Nano Materials, 2023
Dielectric elastomer actuators have attracted growing interest for soft robot due to their large deformation and fast response. However, continuous high-voltage loading tends to cause the electric breakdown of the actuator due to heat accumulation, and ...

Dielectric Elastomer Actuator-Based Multifunctional Smart Window for Transparency Tuning and Noise Absorption

open access: yesActuators, 2021
Soft actuators are compliant material-based devices capable of producing large deformation upon external stimuli. Dielectric elastomer actuators (DEA) are a type of soft actuator that operates on voltage stimuli. Apart from soft robotics, these actuators

Actuation response of polyacrylate dielectric elastomers [PDF]

open access: yesSPIE 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.

Effect of Prestrain on the Actuation Characteristics of Dielectric Elastomers [PDF]

open access: yesPolymers, 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.

Electromechanical analysis and simplified modeling of dielectric elastomer multilayer bending actuator

open access: yesAIP Advances, 2020
Dielectric elastomers can generate large voltage-induced deformation and have been widely used as soft actuators. Dielectric elastomer multilayer structures function as bending-type actuators, enhancing their stiffness and ability to resist external ...

Modeling of a Dielectric Elastomer Bender Actuator

open access: yesActuators, 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.
