15 April 2016 Novel pre-strain method for dielectric electroactive polymers
Author Affiliations +
Dielectric electroactive polymers have demonstrated their significant potential in a variety of applications due to their material strength and elastomeric material properties. Mechanical pre-strain has been shown to enhance material actuation potential significantly. However, with this enhancement comes sacrifices. Mechanical pre-strain imposes a stiff mechanical boundary on the dielectric material in order to maintain the strain. In this research, investigations were made into the mechanisms of mechanical pre-strain and into alternate pre-strain methods. These studies discovered alternate methods capable of producing enhanced pre-strains and final actuation without the addition of the solid strain boundary.
