Stretchable composite monolayer electrodes for low voltage dielectric elastomer actuators

Printing low-voltage dielectric elastomer actuators

Inkjet printing of carbon black electrodes for dielectric elastomer actuators

Inkjet printing is an appealing technique to print electrodes for Dielectric Elastomer Actuators (DEAs). Here we present the preparation and ink-jet printing of a carbon black electrode mixture and characterise its properties. Carbon black has been used extensively in the past because it is very compliant; however, it has a high resistance and can be very dirty to work with. In this paper we sh...

Fluid electrodes for submersible robotics based on dielectric elastomer actuators

Recently, dielectric elastomer actuators (DEAs) have gathered interest for soft robotics due to their low cost, light weight, large strain, low power consumption, and high energy density. However, developing reliable, compliant electrodes for DEAs remains an ongoing challenge due to issues with fabrication, uniformity of the conductive layer, and mechanical stiffening of the actuators caused by...

Multilayer Dielectric Elastomer Actuators with Ion Implanted Electrodes

We present the design, fabrication process and characterization of multilayer miniaturized polydimethylsiloxane (PDMS)-based dielectric elastomer diaphragm actuators. The conductive stretchable electrodes are obtained by lowenergy metal ion implantation. To increase force, decrease the required voltage, and avoid dielectric breakdown, we present here a technique to fabricate multilayer devices ...

Helical dielectric elastomer actuators

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. It is based on a novel helical configuration, suitable for the generation of electrically driven axial contractions and radial expansion...
