ENHANCING THE DIELECTRIC PERMITTIVITY OF ELASTOMERS
2008The electromechanical transduction properties of any dielectric elastomer are intrinsically regulated by the dielectric permittivity of the material. This parameter proportionally controls both the achievable active stresses and strains. Accordingly, a suitable increase of the material permittivity may provide a valuable means to improve the ...

ABSTRACT Life shows us that the distri bution of intellig ence throughout flexible muscular ne tworks is a highly successful solution to a wide range of challenges, for example: human hearts, octopi, or even starfish. Recreating this success in engineered systems requires soft actuator technologies with embedded sensing and intelligence.

Active Elastomer Components Based on Dielectric Elastomers
International Polymer Science and Technology, 2015A new design concept developed at the Fraunhofer LBF allows dielectric elastomers to be integrated efficiently as load-bearing components, serving as both actuator and sensor at the same time. Since the concept is based on perforated metal electrodes with high electrical conductivities, it can also be used for highly dynamic and acoustic applications ...

CHARACTERIZATION OF DIELECTRIC ELASTOMER PLANAR ACTUATORS
Sensors and Microsystems, 2002This 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

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 ...

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.

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 ...

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 ...

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 ...
