Dynamic Modeling of Soft Robotic Dielectric Elastomer Actuator
<p>Dielectric elastomers actuators (DEAs) are among the preferred materials for developing lightweight, high compliance and energy efficient driven mechanisms for soft robots. Simple DEAs consist mostly of a homogeneous elastomeric materials that transduce electrical energy into mechanical …

Large Deformable Soft Actuators Using Dielectric Elastomer and Origami Inspired Structures
… of new configurations, control mechanisms, and actuators based upon its applications. Despite significant improvements in modern robotics, the biologically inspired robots has taken the center stage. Inspired by nature, biologically inspired robots are called ‘soft robots’. Within these robots …

Development of Devices Based on Electrically Actuated Soft Elastomers
Dielectric elastomer (DE) actuators are electromechanical transducers that essentially consist of one layer of an insulating soft elastomer coated on both sides with com- pliant electrodes. When a voltage is applied between the electrodes, an electrostatic pressure deforms the elastomer triggering …

Design and Fabrication of an Electric-Field Induction Motor
This thesis explores a meso-scale micro-actuator of rotational motion based on electric induction. This electric induction motor (EIM) has a cylindrical geometry with a radial air gap between the stator and the rotor. A significant novelty is that the motor does not contain metal, but is rather …

Towards achieving power autonomy in soft-actuated micro aerial robots
… robots. Our robotic platform is driven by a dielectric elastomer actuator (DEA) and generates lift force through flapping wings, a similar mechanism found in flying insects. First, we implemented a dynamic model to optimize the robot components for pairing with an improved DEA to generate a …

Vibrating lubricant-infused porous surface for enhanced liquid droplet transport
… developed SLIPS that can be put in motion by a dielectric elastomer actuator (DEA). This system demonstrates its ability to generate tunable surface wettability that can precisely control droplet dynamics, from complete pinning to fast sliding, and even more complex motions such as droplet …

Comparison of DC Motors and Dielectric Elastomer Actuators For Wearable Wrist Exoskeletons
… required transmission are too large and heavy. Dielectric elastomer actuators (DEAs) may provide a solution to the actuation problem. The focus of this thesis was to compare DC motors with DEAs for use in a wearable wrist exoskeleton to assist with stroke rehabilitation. A simple setup of the …

Dielectric Elastomer Actuators in Electro-Responsive Surfaces Based on Tunable Wrinkling and the Robotic Arm for Powerful and Continuous Movement
Dielectric elastomer actuators (DEAs) have been used for artificial muscles for years. Recently the DEA-based deformable surfaces have demonstrated controllable microscale roughness, ease of operation, fast response, and possibilities for programmable control. DEA muscles used in bioinspired …
