Abstract: A linear displacement device includes at least one artificial muscle actuator, an arm attached to the at least one artificial muscle, a body that is restricted to move along a line, and a stationary channel that restricts the motion of the body to linear motion. The at least one artificial muscle actuator causes the body to move along the line. The body is further restricted to move along a surface of the arm and the at least one artificial muscle actuator is a rotational muscle actuator. Additionally, the arm rotates in concert with the at least one artificial muscle actuator.

Abstract: Techniques are described for transferring nanofiber forests using transfer films that either lack a conventional adhesive at the substrate-nanofiber forest interface or that include a diffusion barrier that prevents diffusion of adhesive molecules (or other polymer molecules mobile at ambient temperatures) into the nanofiber forest. These techniques can be applied to single layer nanofiber forests or stacks of multiple nanofiber forest. By selecting the bond strength between the nanofiber forest and the transfer films, the nanofibers can be aligned in a common direction that includes, but is not limited to, perpendicular to a substrate or transfer film.

Abstract: An insulated nanofiber having a continuous nanofiber collection extending along a longitudinal axis with an outside surface and an inside portion is described. A first material infiltrates the inside portion, where the outside surface of the nanofiber collection is substantially free of the first material. An electrically-insulating second material coats the outside surface of the nanofiber collection. A method of making an insulated nanofiber collection is also disclosed.

Abstract: An array of discrete nanofiber films that are physically separated from one another are described. Techniques for forming the nanofiber film array are also described. Techniques for forming these structures include placing a suspension of nanofibers and/or nanoparticles on a patterned substrate. A pressure differential is applied, drawing the solvent of the suspension through holes in a mask. The nanofibers collect on an impermeable layer on the mask in a pattern corresponding to the negative features (grooves, holes, trenches) of the mask as the solvent is flowed through the holes.

Abstract: A density of a nanofiber sheet can be changed using an edged surface, and in particular an arcuate edged surface. As described herein, a nanofiber sheet is drawn over (and in contact with) an arcuate edged surface. Depending on whether the arcuate surface facing a direction opposite the direction in which the nanofiber sheet is being drawn is convex or concave determines whether the nanofiber sheet density is increased relative to the as-drawn sheet or decreased relative to the as-drawn sheet.

Abstract: An actuator and method of manufacturing an actuator that includes a core fiber with polymers aligned along the length of the core fiber, and a wire that is wound around and fixed to the core fiber. The winding of the wire is engineered based on the torsional actuation. Upon heating the core fiber, the wire impedes radial expansion of the core fiber and converts the radial expansion into a torsional actuation.

Abstract: A nanofiber forest that includes a pattern or shape can be transferred to a substrate. The nanofiber forest can be configured to have any perimeter and/or internal shape or pattern using a stencil technique and/or using an engraving technique. This pattern can be transferred as a “negative image” of a corresponding pattern in a stencil or as a “positive image” by engraving the pattern directly into the nanofiber forest. For either type of pattern formation, the patterned nanofiber forest is transferred by applying a substrate to the pattern or to a nanofiber forest covered by a patterned stencil. Pressure is then applied causing the exposed surface of the nanofiber forest or pattern of nanofiber forest to adhere to the substrate.
