Articles comprising fibres that change colour when they are stretched, thereby giving an indication of the tension being applied to the article. The present invention can be used with a variety of articles which require tension to be applied to achieve maximum functionality. These articles can include garments, such as compression garments, shirts, shorts, pants, socks, underwear, or hats; bandages, such as compression bandages; shoelaces; shoes; securities, sutures, ropes or cables.
摘要:
Articles comprises iron oxide colloidal nanocrystals arranged within chains, wherein the chains of nanocrystals are embedded within a material used to form the article or a transfer medium used to transfer a color to the article are described. The material or transfer medium includes elastic properties that allow the nanocrystals to display a temporary color determined by the strength of an external force applied to the article, and the material or transfer medium includes memory properties that cause the displayed temporary color to dissipate when the external force is removed, wherein the dissipation of the displayed temporary color is sufficiently slow as to be visually observable by an average observer's unaided eye.
摘要:
Nanophononic metamaterials and methods for reducing thermal conductivity in at least partially crystalline base material are provided, such as for thermoelectric energy conversion. In one implementation, a method for reducing thermal conductivity through an at least partially crystalline base material is provided. In another implementation, a nanophononic metamaterial structure is provided. The nanophononic metamaterial structure in this implementation includes: an at least partially crystalline base material configured to allow a plurality of phonons to move to provide thermal conduction through the base material; and at least one nanoscale locally resonant oscillator coupled to the at least partially crystalline base material. The at least one nanoscale locally resonant oscillator is configured to generate at least one vibration mode to interact with the plurality of phonons moving within the base material and slowing group velocities of at least a portion of the interacting phonons and reduce thermal conductivity through the base material.

摘要:
Systems and methods of manipulating a color displayed by an article of wear comprising iron oxide colloidal nanocrystals arranged within chains are described. Steps may include forming the article of wear from a raw material that include the chains of nanocrystals, applying a magnetic field to the raw material, applying energy to at least some of the chains of nanocrystals to soften materials within the raw material immediately surrounding the chains of nanocrystals to which the energy is applied, adjusting a strength of the magnetic field to control the color displayed by the raw material, removing the energy to allow the materials within the raw material immediately surrounding the chains of nanocrystals to harden and fix a location of the nanocrystals within the chains, and removing the magnetic field.
