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: 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.
