  • Patent number: 11491004
    Abstract: A carbon nanotube (CNT) artificial muscle valve includes a hollow CNT tube including: a plurality of CNT sheets wrapped in the form of a hollow tube; and a guest material disposed between the CNT sheets and that permeates the CNT sheets. At least one portion of the hollow CNT tube collapses in response to a pressure of a fluid in the hollow CNT tube exceeding a predetermined pressure. The at least one portion of the hollow CNT tube collapses because the at least one portion of the hollow CNT tube generates a torque non-uniformity relative of a remaining portion of the hollow CNT tube.

  • Patent number: 11434881
    Abstract: An apparatus and method of manufacturing an apparatus that includes a rectangular frame, a first load bearing conductive support bisecting the rectangular frame lengthwise, and two artificial muscle actuators disposed on the same sides of the rectangular frame as the first load bearing conductive support on opposite sides of the first load bearing conductive support is disclosed. The apparatus includes a non-conductive platform, where the width of the frame is sufficiently wide to prevent the non-conductive platform from touching the sides of the frame when rotated about the axis of the load bearing support. The apparatus includes a device disposed in the center of the non-conductive platform. Individual actuation of the artificial muscle actuators rotates the non-conductive platform about the axis of the first load bearing conductive support.

  • Publication number: 20210116152
    Abstract: Cooling by a twist-untwist process, by a stretch-release process for twisted, coiled, or supercoiled yarns or fibers, and methods and systems thereof. High mechanocaloric cooling results from release of inserted twist or from stretch release for twisted, coiled, or supercoiled fibers, including natural rubber fibers, NiTi wires, and polyethylene fishing line. Twist utilization can increase cooling and cooling efficiencies. A cooler using twist insertion and release can be shorter and smaller in volume than a cooler that requires a large elastomeric elongation. The cooler system can be utilized in mechanochromic textiles and remotely readable tensile and torsional sensors.
