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.
