Photothermal modulated dielectric elastomer actuator for resilient soft robots [PDF]

Nature Communications, 2022
Tough and healable elastomers are promising materials to realize resilient soft robots but mechanical enhancements often lead to higher stiffness that deteriorates actuation strains.

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
