Dissipation factor of acrylic dielectric elastomer--an experimental study.

Maximizing the Energy Density of Dielectric Elastomer Generators Using EquiBiaxial Loading

Dielectric elastomer generators (DEGs) for harvesting electrical energy from mechanical work have been demonstrated but the energy densities achieved are still small compared with theoretical predictions. In this study, signifi cant improvements in energy density (560 J/kg with a power density of 280 W/ kg and an effi ciency of 27%) are achieved using equi-biaxial stretching, a mechanical loadi...

River Devices to Recover Energy with Advanced Materials River DREAM

This report describes the development and testing of a Galloping Hydro Electric Energy Device (GHEED) which is intended to utilize a Dielectric Elastomer Generator (DEG). The mechanical side of the GHEED includes a shape morphing element, and has been designed to convert the kinetic energy of low head and/or turbulent flows into repeating, oscillating motion. The intent is to couple this motion...

Study of Fibroblast Cells Behavior on the Acrylic Acid Co2 Pulsed Laser Grafted Silicone Elastomer for Tissue Engineering Application

Modeling of a Dielectric Elastomer Bender Actuator

The current smallest self-contained modular robot uses a shape memory alloy, which is inherently inefficient, slow and difficult to control. We present the design, fabrication and demonstration of a module based on dielectric elastomer actuation. The module uses a pair of bowtie dielectric elastomer actuators in an agonist-antagonist configuration and is seven times smaller than previously demo...

The Effect of Primer on Bond Strength of Silicone Prosthetic Elastomer to Polymethylmethacrylate: An in vitro Study.

INTRODUCTION The aim of the study is to evaluate interfacial bond strength between silicone prosthetic elastomers and polymethylmethacrylate (PMMA). MATERIALS AND METHODS Silicone elastomers were attached to PMMA and a total 120 specimens were fabricated which were then subdivided into 12 sub-groups. Each sample was then subjected to laboratory test to determine the bond strength. The specime...
