A Review of Cooperative Actuator and Sensor Systems Based on Dielectric Elastomer Transducers
Actuators, 2023 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 ...

Balloon dielectric elastomer actuator speaker
Applied Acoustics, 2019 Abstract A balloon dielectric elastomer actuator (DEA) speaker is constructed by forming a disk-shaped DEA film into a sphere using air, increasing its surface area by 3033%. Sound is generated via expansion and contraction. Shaping the DEA film into a sphere decreases the film thickness and applies a significant amount of pre-strain (prestretch) to ...

Research on control of dielectric elastomer actuator based on BAS-PID algorithm
Xi'an Gongcheng Daxue xuebao, 2021 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]
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.
