Actuation capability of a dielectric elastomer balloon actuator

2016 12th IEEE International Conference on Control and Automation (ICCA), 2016
Dielectric elastomers show great promise for soft actuators. As the allowable deformation range of dielectric elastomers is strictly limited by the material failures, the actuation ability of a dielectric elastomer actuator is accordingly bounded. Although the material failures have been well studied, little literature has been released regarding the ...

CHARACTERIZATION OF DIELECTRIC ELASTOMER PLANAR ACTUATORS

Sensors and Microsystems, 2002
This work intends to extend the electromechanical characterisation of dielectric elastomer actuators. Planar actuators were realised with a 50m-thick film of an acrylic elastomer coated with compliant electrodes. The isotonic transverse strain, the isometric transverse stress and the driving current, due to a 2 s high voltage impulse, were measured for

Improved Materials for Dielectric Elastomer Actuators

Volume 1: Advanced Energy Systems; Advanced and Digital Manufacturing; Advanced Materials; Aerospace, 2008
Dielectric elastomers are an emerging class of electroactive polymers for electromechanical transduction. A broad application of dielectric elastomer actuators (DEA) is limited by the high voltage necessary to drive such devices. The development of novel elastomers offering better intrinsic electromechanical properties is one way to solve the problem ...

Dielectric elastomer actuators for tactile displays

World Haptics 2009 - Third Joint EuroHaptics conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2009
In this paper we discuss dielectric elastomer actuators (DEA) as one of the most promising technologies in electroactive polymers (EAP). For tactile display applications a large number of actuator elements is essential. The multilayer technology presented here offers the possibility to build up independent actuators and arrays at a high density within ...

Granularly Coupled Dielectric Elastomer Actuators

IEEE/ASME Transactions on Mechatronics, 2011
Dielectric elastomer actuators (DEAs) have been demonstrated to represent today a high-performance technology for electroactive polymer mechatronics. As a means to improve versatility and safety of DEAs, so-called “hydrostatically coupled” DEAs (HC-DEAs) have recently been shown to offer new opportunities.

Twisted Dielectric Elastomer stack Actuator

2016 13th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2016
The purpose of this research is to make an actuator which is easily adaptable to use as artificial muscle by improving structure of stack-type Dielectric Elastomer Actuator (DEA). In contrast with previous stack-type actuator, Single body Dielectric Elastomer stack Actuators (SDEAs) is connected as single body without external frame so that it can be ...
