Dielectric elastomer actuator biased by magnetorheological elastomer with permanent magnet [PDF]
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 ...

Feasibility of a Dielectric Elastomer Augmented Aorta [PDF]
Advanced Science, 2021 Although heart transplantation is a gold standard for severe heart failure, there is a need for alternative effective therapies. A dielectric‐elastomer aorta is used to augment the physiological role of the aorta in the human circulatory system.

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 ...

Wireless Powered Dielectric Elastomer Actuator [PDF]
IEEE 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.

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
