Article
This paper focuses on the electromechanical evaluation of combinations of novel sub-micron metal and carbon thin film electrodes for dielectric elastomers. The thin film electrodes are sputtered either onto 37.5 % biaxially pre-stretched polydimethylsiloxane (PDMS)-foils or on 57.5 % pre-stretched foils under pure shear conditions. The electrodes a...

This paper presents a novel design method for high-frequency dielectric elastomer actuator (DEA) applications. A DEA consist of a mechanically pre-stretched elastomer film sandwiched between two compliant electrodes, which expands when subject to a high voltage. While the design of low-frequency DEA applications is generally well understood, up to...

Thermische Formgedächtnislegierungen (FGL) gehören zur Gruppe der intelligenten Materialien. Sie haben die höchste bekannte Energiedichte unter den bekannten Aktuatoren und in Kombination mit ihren intrinsischen Self-Sensing Fähigkeiten ermöglichen sie den Aufbau extrem leichter und kompakter Aktor-Sensor-Systeme. Da die Datenblätter der Hersteller...

Zusammenfassung: Dielektrische Elastomeraktoren (DEA) erlauben kompakte, lautlose und leichte Systeme mit einer großen Aktuierungsbandbreite bis in den Kilohertzbereich. DEAs bestehen im Wesentlichen aus einer dünnen Elastomerfolie die beidseitig mit einer elektrisch leitfähigen, dehnbaren Elektrode beschichtet ist. Wird dieser Kondensatoraufbau mi...

Dielectric elastomer actuators (DEA) enable to build compact, silent and lightweight systems capable of a large actuation bandwidth up to the kHz range. They consist of a thin elastomer film between two electrically conductive and flexible electrodes. If a high voltage is supplied to a DEA, the opposing electrical charges on the two electrodes resu...

The structure of dielectric elastomer actuators (DEAs) is based on a thin elastomer layer, which is sandwiched in-between compliant electrodes. This capacitor like structure enables to build lightweight and energy efficient actuators with high design flexibility. An applied high voltage leads to a thickness compression and to a simultaneous area ex...

Dielectric elastomers represent a relatively new technology with high potentials for actuators’ applications. Thanks to their lightweight, fast operations, energy efficiency, low power consumption, large deformations, and high scalability, dielectric elastomers permit to develop novel mechatronic systems capable of overperforming standard actuation...
Conference Paper
Full-text available
Dielectric elastomer (DE) membrane actuators are known to provide high strokes compared to DE stack actuators. A graphical method can be used to design a membrane actuator system (combination of membrane DEA and biasing elements) for a specific application. This method considers the equilibrium of forces at steady-state, and thus completely neglect...

This paper presents on finite element modeling and simulation of dielectric elastomer actuators (DEAs) coupled with articulated structures. DEAs have proven to represent an effective transduction technology for the realization of large-deformation, low-power consuming, and fast mechatronic actuators. However, the complex dynamic behavior of the mat...

Unter dem Begriff eines dielektrischen Elastomer-Membran Aktors wird ein mechatronisches Antriebssystem verstanden, das durch die Kopplung mehrerer Vorspannelemente und einer dielektrischen Elastomer-Membran Bewegungen ausführen kann. Diese Membranen sind eine besondere Bauform der dielektrischen Elastomere (DE), welche eine neue Technologie im Ber...

This paper presents a finite element model implementation for a first prototype of a mechanical switch actuated by a Dielectric Elastomer (DE) membrane. Due to their high compactness, fast actuation, and high energy efficiency, DE membranes represents an effective alternative to conventional motion actuators in many possible applications. The appli...
