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

Reconfigurable shape-morphing dielectric elastomers using spatially varying electric fields [PDF]
Nature Communications, 2019 Electric fields can produce strains in soft elastomers but a generalizable method for changing the Gaussian curvature has not been devised. Here the authors demonstrate voltage-tunable shape morphing using a spatially inhomogeneous electric field ...

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 ...

Monolithic Stacked Dielectric Elastomer Actuators [PDF]
Frontiers 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

International Journal of Engineering and Advanced Technology, 2021 This paper appraisals state-of-the-art dielectric elastomer actuators (DEAs) and their forthcoming standpoints as soft actuators which have freshly been considered as a crucial power generation module for soft robots. DEs behave as yielding capacitors, expanding in area and attenuation in thickness when a voltage is applied.
