Theory of dielectric elastomers
Acta Mechanica Solida Sinica, 2010In response to a stimulus, a soft material deforms, and the deformation provides a function. We call such a material a soft active material (SAM). This review focuses on one class of soft active materials: dielectric elastomers. When a membrane of a dielectric elastomer is subject to a voltage through its thickness, the membrane reduces thickness and ...

Improved Materials for Dielectric Elastomer Actuators
Volume 1: Advanced Energy Systems; Advanced and Digital Manufacturing; Advanced Materials; Aerospace, 2008Dielectric 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, 2009In 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 ...

Twisted Dielectric Elastomer stack Actuator
2016 13th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2016The 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 ...

A rotary joint based on dielectric elastomer
2013 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2013Biological joints have advantages such as compact structure and multi degree-of-freedom (DOF) rotation. To emulate a biological joint, a 2-DOF rotary joint actuated by dielectric elastomer (DE) is designed, in which DE acts as muscles. Based on the analysis of the working principle of the joint, a mechanism is presented to increase its angular ...

Hydrostatically Coupled Dielectric Elastomer Actuators
IEEE/ASME Transactions on Mechatronics, 2010Within the emerging field of polymer-based mechatronics, soft materials showing intrinsic electromechanical transduction properties are being largely studied to develop new types of actuators. Among them, so-called dielectric elastomer (DE) actuators are one of the most promising.

Electroelasticity of dielectric elastomers
Abstract Elastomeric dielectric materials with ground-state shear moduli in the kilopascal range can undergo over 100% deformation under large applied voltages. These soft electroactive materials are the focus of this chapter, which formulates a coupled nonlinear electro-elasticity theory.Lallit Anand +2 more
