Dielectric elastomer memory

SPIE Proceedings, 2011
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.

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.

Hydrostatically Coupled Dielectric Elastomer Actuators

IEEE/ASME Transactions on Mechatronics, 2010
Within 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.

Dynamic response of dielectric elastomers

International Journal of Non-Linear Mechanics, 2004
Dielectric elastomers have received a great deal of attention recently for effectively transforming electrical energy to mechanical work. Their large strains and conformability make them enticing materials for many new types of actuators. Unfortunately, their non-linear material behavior and large deformations make actual devices difficult to model ...

Active Elastomer Components Based on Dielectric Elastomers

International Polymer Science and Technology, 2015
A 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 ...

Folded dielectric elastomer actuators

Smart Materials and Structures, 2007
Polymer-based linear actuators with contractile ability are currently demanded for several types of applications. Within the class of dielectric elastomer actuators, two basic configurations are available today for such a purpose: the multi-layer stack and the helical structure.

Helical dielectric elastomer actuators

Smart Materials and Structures, 2005
This paper presents a new type of contractile polymer-based electromechanical linear actuator. The device belongs to the class of dielectric elastomer actuators, which are typically capable of undergoing large deformations induced by an applied electric field.

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
