Abstract: Shape memory yarns described herein include twisted microfilaments made from a shape memory alloy that may provide superelastic or shape memory properties. The shape memory yarns are formed into coils that provide a high degree of actuation or elasticity along an axis of the coiled shape memory yarn, and may have relatively low porosity, low rigidity, and/or low change of volume compared to shape memory coils formed from solid structures. Coiled shape memory yarns may provide further tailorability of a superelastic or shape memory response of a system or device incorporating the coiled shape memory yarns through various coil parameters, such as coil pitch or density, or torque balancing, such as heat treating or plying the coiled shape memory yarns.

Abstract: A power transmission belt includes a belt body made of an elastomer, and a cord made of carbon fibers and provided to be embedded in the belt body and to form a helical pattern having a pitch in the belt width direction. When the cord is viewed from a side orthogonal to its length direction, an angle θ of an outermost filament in the filament bundle of the carbon fibers forming the cord with respect to the length direction of the cord is 8° or more to 20° or less.

Abstract: Actuators (artificial muscles) comprising twist-spun nanofiber yarn or twist-inserted polymer fibers generate actuation when powered electrically, photonically, chemically, thermally, by absorption, or by other means. These artificial muscles utilize polymer fibers non-coiled or coiled yarns and can be either neat or comprising a guest. Devices comprising these artificial muscles are also described. In some embodiments, thermally-powered polymer fiber torsional actuator has a twisted, chain-oriented polymer fiber that has a first degree of twist at a first temperature and a second degree of twist at a second temperature in which the bias angles of the first degree and second degree of twist are substantially different.

Abstract: The invention relates to an arrangement comprising a visible seam, which is arranged in a sheet material part. The arrangement also includes a lighting apparatus, which is arranged beneath an underside of the sheet material part. The visible seam has an upper thread and a lower thread. The lower thread extends along the underside of the sheet material part in a direction (R). The upper thread has first thread portions along the upper side of the sheet material part and is guided, at stitch holes formed during the sewing process, through said stitch holes via second thread portions. By means of the lighting apparatus, emitted light passes into the second thread portions, into the stitch holes, and from there into the first thread portions. Some of the light propagates along the first thread portions, starting from an adjacent second thread portion, whereas another portion of the light exits from the first thread portion. In this way, the upper thread of the visible seam is illuminated.

Abstract: Actuators (artificial muscles) comprising twist-spun nanofiber twist-inserted polymer fibers generate tensile actuation when powered electrically, photonically, chemically, thermally, by absorption, or by other means. These artificial muscles utilize coiled polymer fibers and can be either neat or comprising a guest. In some embodiments, the coiled polymer fibers actuator can be incorporated into an article, such as a textile, braid, clothing, smart packaging, or a mechanical system, and the coiled polymer fiber in the coiled polymer fiber actuator can have a stroke amplification factor of 5 or greater.
