    Abstract: Methods, systems, and apparatus for fabricating nanofiber yarn at rates of at least 30 m/min (1.8 kilometers (km)/hour (hr)) using a “false twist” nanofiber yarn spinner and a false twist spinning technique are disclosed. In a false twist spinning technique, a twist is introduced to nanofibers in a strand by twisting the nanofibers at points between ends of the strand. This is in contrast to the “true twist” technique where one end of a strand is fixed and the opposing end of the strand is rotated to introduce the twist to intervening portions of yarn.

    Abstract: An artificial muscle tentacle and method for manufacturing an artificial muscle tentacle, and a computer readable medium for controlling an artificial muscle tentacle are disclosed. The artificial muscle tentacle includes two spacers and a central core that connects the two spacers. The artificial muscle tentacle also includes at least two Z-Twist actuators and at least two S-Twist actuators. The Z-Twist actuators and the S-Twist actuators are disposed around the central core and in between the two spacers connecting the two spacers. The actuation of one or more of the Z-Twist actuators and the S-Twist actuators actuates the artificial muscle tentacle.

    Abstract: A method for manufacturing a separable artificial muscle fastener includes: securing one or more muscle loops of an artificial muscle fiber to a substrate such that at least a portion of the one or more muscle loops extends out from the substrate; annealing the artificial muscle fiber to retain the one or more muscle loops; and cutting and removing a portion of the one or more muscle loops to transform the one or more muscle loops into one or more muscle hooks. When the one or more muscle hooks are engaged with one or more holders, actuating the one or more muscle hooks disengages the one or more muscle hooks from the one or more holders.

    Abstract: Methods, system, and apparatus for producing an actuator device are disclosed. The method may include twisting a muscle fiber; coiling the twisted muscle fiber about a mandrel; securing the muscle fiber onto the mandrel using a securing means; heating the muscle fiber to a predetermined temperature using a heating means; and removing the coiled muscle fiber from the mandrel. The twisting, coiling, securing, heating, and removing is a process that is continued until the muscle fiber is a desired length.

    Abstract: An actuator device that includes at least one fiber, and at least one first coating is disclosed. The first coating encloses the at least one fiber. The actuator device may include a plurality of fibers and/or a conducting material. The coatings may enclose the plurality of fibers, or each individual fiber. The coatings may provide moisture protection, UV protection, saline protection, and oxidation protection. The coating may be thermally and electrically conducting or insulating, depending on the specific function and environment of the actuator device.

    Abstract: Nerve scaffolds are described that include a tubular outer housing fabricated from a biocompatible polymer, within which are disposed a plurality of carbon nanofiber yarns. The carbon nanofiber yarns, which can be separated by distances roughly corresponding to an average nerve fiber diameter, provide surfaces on which nerve fibers can regrow. Because the proximate carbon nanofiber yarns can support individual nerve fibers, a nerve can be regenerated with a reduced likelihood of undesirable outcomes, such as nerve pain or reduced nerve function.

    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.
