Abstract
A patterned dielectric elastomer actuator is disclosed which includes a series of thin parallel elastomer filaments, separated by certain distances sandwiched between a pair of rigid electrodes. The elastomer filaments and air acts as a patterned dielectric layer. The elastomer filaments can compress laterally from a circular cross-section to an elliptical shape when a voltage is applied between the rigid electrodes. The elastomer filaments can touch laterally, which implies no further squeezing in order to provide a minimal secure distance between the rigid electrodes. The dielectric elastomer actuator can be fabricated utilizing a reel-to-reel fabrication process with the thin elastomer filaments fabricated ahead of time, by extrusion techniques and cured completely before storing on reels.
