    Abstract: Systems 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 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.
