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 nanofiber sheet is described that is composed of a substrate and a layer of oriented nanofibers. Nanofibers of the sheet can be oriented in a common direction. In some orientations, light absorbent sheets can absorb over 99.9%, and in some cases over 99.95%, of the intensity of light incident upon the sheet. Methods for fabricating a light absorbent sheet are also described.

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.

Abstract: Techniques are described for controlling widths of nanofiber sheets drawn from a nanofiber forest. Nanofiber sheet width can be controlled by dividing or sectioning the nanofiber sheet in its as-drawn state into sub-sheets as the sheet is being drawn. A width of a sub-sheet can be controlled or selected so as to contain regions of uniform nanofiber density within a sub-sheet (thereby improving nanofiber yarn consistency) or to isolate an inhomogeneity (whether a discontinuity is the sheet (e.g., a tear) or a variation in density) within a sub-sheet. Techniques for dividing a nanofiber sheet into sub-sheets includes mechanical, corona, and electrical arc techniques.

Abstract: Nanofiber based sensors are described that can be used to detect analytes in biological or non-biological contexts. Each sensor includes at least two nanofiber yarns that are spaced apart from one another so as to avoid electrical (or physical) contact. Each nanofiber yarn of the nanofiber sensor includes a sensing region that is in electrical contact with the rest of the corresponding nanofiber yarn. The sensing regions of the at least two nanofibers are treated with complementary sensing agents so that when the sensing regions (and the corresponding sensing agents) are exposed to the analyte to be detected, an electrical response is detected. This response is then communicated through one or more of the nanofiber yarns for interpretation by a processor.
