Enhancing the Electromechanical Coupling in Soft Energy Harvesters by Using Graded Dielectric Elastomers [PDF]

open access: yesMicromachines, 2021
Soft dielectric elastomers can quickly achieve large deformations when they are subjected to electromechanical loads. They are widely used to fabricate a number of soft functional devices. However, the functions of soft devices are limited to the failure

Degradation patterns of silicone-based dielectric elastomers in electrical fields [PDF]

open access: yesInternational Journal of Smart and Nano Materials, 2018
Silicone elastomers have been heavily investigated as candidates for the flexible insulator material in dielectric elastomer transducers and are as such almost ideal candidates because of their inherent softness and compliance.

Dielectric elastomer actuators [PDF]

open access: yesJournal 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 ...

Proposal of a generic constitutive model for deformation-dependent dielectric constant of dielectric elastomers

open access: yesEngineering Science and Technology, an International Journal, 2021
Dielectric elastomers (DEs) are electroactive polymers that could be used as soft actuators, stretchable generators and sensors. Their performance is dependent on both their mechanical and dielectric properties.

Monolithic Stacked Dielectric Elastomer Actuators [PDF]

open access: yesFrontiers in Robotics and AI, 2021
Dielectric elastomer actuators (DEAs) are a promising actuator technology for soft robotics. As a configuration of this technology, stacked DEAs afford a muscle-like contraction that is useful to build soft robotic systems. In stacked DEAs, dielectric and electrode layers are alternately stacked. Thus, often a dedicated setup with complicated processes
