    Abstract: A sensor may include a knitted pocket and loose yarn that is inside a cavity of the pocket. In some cases, this loose yarn is neither woven, nor knit, nor otherwise part of a fabric. A resistive pressure sensor may include a knitted pocket and loose conductive yarn that is inside the pocket. Pressure applied to the pocket may compress the loose yarn, which may increase the number of electrical shorts between different parts of the loose yarn, which in turn may decrease the electrical resistance of the loose yarn. A capacitive sensor may include a knitted pocket and insulative loose yarn that is inside the pocket. A strain sensor may include knitted conductive pleats. Electrical shorts may occur in contact areas where neighboring pleats meet. As the strain sensor stretches, these contact areas may become smaller, causing the electrical resistance of the pleats as a group to increase.

    Abstract: A fabric having particularly good translucent properties with regard to UVA and UVB radiation, in particular for use in garments for the sport and leisure sector, with the transparency being reduced at the same time. The fabric comprises a first yarn made of cellulose-based fiber or regenerated fiber, and a second yarn made of polymer fiber. The proportion by weight of the first and second yarns is at least 80% by weight. The wale density is in the range from 10 to 30 per cm and the course density is in the range from 15 to 33 per cm. The second yarn has a fineness in the range from 45 to 300 dtex and the first yarn has a fineness in the range from 150 to 300 dtex. The grammage of the fabric is between 70 and 150 g/m{circumflex over ( )}2.

    Abstract: A fabric-based item may include fabric formed from intertwined strands of material such as intertwined strands of tubing. The strands of material may include electrophoretic ink formed from charged nanoparticles of different colors in fluid. The electrophoretic ink may be contained within strands of tubing or may be enclosed within encapsulation structures such as encapsulation spheres. Encapsulation spheres or other encapsulation structures may be embedded in clear polymer binder within tubing or other strands. Electroluminescent particles may be included in the clear polymer binder. Electric fields can be applied to the electrophoretic ink in a given area of the fabric using conductive strands that overlap the area, using conductive electrodes such as transparent conductive electrodes on strands of tubing, using coaxial electrodes, or using other electrode structures.
