Research on control of dielectric elastomer actuator based on BAS-PID algorithm
Because the actuator composed of the dielectric elastomer has a viscoelastic effect during the driving process of the soft robot, which makes it difficult to accurately control the robot, a kind of beetle antennae search(BAS) algorithm optimization PID ...

Wireless Powered Dielectric Elastomer Actuator [PDF]
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.

A Review of Cooperative Actuator and Sensor Systems Based on Dielectric Elastomer Transducers
This paper presents an overview of cooperative actuator and sensor systems based on dielectric elastomer (DE) transducers. A DE consists of a flexible capacitor made of a thin layer of soft dielectric material (e.g., acrylic, silicone) surrounded with a ...

Preparation and Dielectric Sensitivity of Polyurethane Composite Fiber Membrane Filled with BaTiO3
Polyurethane dielectric elastomer (PUDE) is considered a potential underwater flexible actuator material due to its excellent designability and environmental tolerance at the molecular level. Currently, the application of the polyurethane elastomer as an

Actuation response of polyacrylate dielectric elastomers [PDF]
Polyacrylate dielectric elastomers have yielded extremely large strain and elastic energy density suggesting that they are useful for many actuator applications. A thorough understanding of the physics underlying the mechanism of the observed response to an electric field can help develop improved actuators.
