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.

Abstract: A hinge-type actuator device in accordance with the present disclosure may include a first and second paddle, a first and second artificial muscle actuator segment, and a plurality of contacts, where the first and second artificial muscle actuator segments are actuated via the contacts, actuation of the first artificial muscle actuator segment causes the first and second paddle to open the hinge-type actuator, and actuation of the second artificial muscle actuator segment causes the first and second paddle to dose the hinge-type 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 actuator device that includes a first actuating segment of an artificial muscle fiber, where one end of the first actuating segment is connected to a first terminal and the other end of the first actuating segment is connected to a second terminal. The device also includes a second actuating segment of an artificial muscle fiber, where one end of the second actuating segment is connected to a third terminal and the other end of the second actuating segment is connected to a fourth terminal. The device also includes a paddle disposed on both the first and second actuating segments and a heating provision disposed on the first and second actuating segments. The heating provision independently provides energy in the form of heat to the first and second actuating segments, and the actuator device moves rotates the paddle to a desired position through activating the first or second actuating segments.

Abstract: A filtered nanofiber film can be used as an intervening layer between the nanofiber structure (e.g., a drawn nanofiber sheet and/or a nanofiber forest) and a final substrate. Filtered nanofiber films can adhere to other types of nanofiber structures (e.g., drawn nanofiber sheets and/or nanofiber forests) and also exhibit adhesion to non-nanofiber surfaces. Thus, when used as an intervening layer between another type of nanofiber structure and a final substrate, a filtered film can increase adhesion therebetween. Filtered nanofiber films can also be used as a releasable protective film to prevent contamination of a confronting major surface of the nanofiber structure.

Abstract: A nanofiber forest is described that has been processed to increase a number of nanofibers per unit area (referred to as “areal density” or, equivalently, “density”) compared to the nanofiber forest in its as-synthesized state. This increase in areal density is accomplished by physically manipulating a deformable substrate on which the nanofiber forest is disposed. At a high level, this physical manipulation begins by transferring the nanofiber forest from a growth substrate to a deformable substrate. A surface area of the deformable substrate is reduced relative to a surface area of the substrate when the nanofiber forest was attached. This reduction in area causes the nanofibers in the forest to move closer to one another, thus increasing the number of nanofibers per unit area.
