A flexible fiber substrate and a flexible display device including the same are provided. The flexible fiber substrate includes: an insulating body woven from an insulating fiber and a patterned conductive member made of a conductive fiber. The conductive member and the insulating body are fixed to each other by interlacing, and the conductive member is touchable from outside of the flexible fiber substrate.

Conductive yarns in a knitted fabric may include insulating cores covered with metal layers that form signal paths. Open circuits may be formed in the yarns by removing metal from the insulating cores at selected locations within the yarns. The fabric may be formed from rows of interlocked loops of the yarn. The open circuits may be located on the loops so that each loop with an open circuit has a first segment of the metal layer that is separated from a second segment of the layer by a portion of the loop from which the metal layer has been removed. Each electrical component may have terminals that span a respective one of the open circuits and that are shorted respectively to the metal of the first and second segments.

Devices and methods for remotely monitoring and treating wounds or wound infections are disclosed. Systems including the described devices are also disclosed.

Strands of material may be intertwined using weaving techniques, knitting techniques, non-woven or entanglement techniques, or braiding techniques. Fabric that is formed from the strands of material may be used in forming a fabric-based item. The fabric based item may include electrical components. The strands may include conductive strands that form signal paths. The signal paths can carry electrical signals associated with operation of the electrical components. Each strand may have an elongated core and a coating. Strands may also include intermediate layers between the cores and coatings. The cores, intermediate layers, and coatings may be formed from polymer without conductive filler, polymer with conductive filler, and/or metal. A polymer core may be provided with recesses to help retain subsequently deposited layers such as a metal coating layer. The recesses may be grooves that extend along the longitudinal axis of the core.

A conductive interconnect structure comprises a polymeric substrate (e.g., a thermoplastic) and a plurality of compliant conductive microstructures (e.g., conductive carbon nanofibers) embedded in the polymeric substrate. The microstructures can be arranged linearly or in a grid pattern. In response to heating, the polymeric substrate transitions from an unshrunk state to a shrunken state to move the microstructures closer together, thereby increasing an interconnect density of the compliant conductive microstructures. Thus, the gap or pitch between adjacent microstructures is reduced in response to heat-induced shrinkage of the polymeric substrate to generate finely-pitched microstructures that are densely pitched, thereby increasing the current-carrying capacity of the microstructures. The polymeric material can be heated to conform or form-fit to planar and non-planar surfaces/geometries, and can be selectively heated at various portions to tailor or customize the interconnect density of the microstructures at selected portions. Associated electrical conducting assemblies and methods are provided.

A system for continuously humidifying a textile electrode during its use by a human is disclosed. The electrode can be part of a garment or textile where the textile electrode is positioned against the skin. A reservoir positioned against the electrode and opposite the user's skin can be made from a material with hydrophilic and hydrophobic properties, such as natural wool or a skincore material. The reservoir receives and retains moisture from the user's skin through the electrode, as well as from a pre-wetting of the exposed user-facing side of the electrode. A seal can surround the reservoir and the electrode, with the seal extending beyond electrode. The seal can be a patch with heat activated adhesive at the edge to flow the textile to form a moisture barrier around the electrode. An electrical contact on the electrode can connect conductive wires from outside the seal to the electrode.

A fluoride-based resin prepreg and a circuit substrate using the same are provided. The fluoride-based resin prepreg includes 100 PHR of a fluoride-based resin and 20 to 110 PHR of an inorganic filler. Based on a total weight of the fluoride-based resin, the fluoride-based resin includes 10 to 80 wt % of polytetrafluoroethylene (PTFE), 10 to 50 wt % of fluorinated ethylene propylene (FEP), and 0.1 to 40 wt % of perfluoroalkoxy alkane (PFA). The circuit substrate includes a fluoride-based resin substrate and a circuit layer that is formed on the fluoride-based resin substrate.

A machine knittable hybrid yarn for providing conductive traces through a textile is disclosed. The hybrid yarn includes conductive wires coated with an insulating material and twisted together with a nonconductive yarn. The nonconductive yarn is from a strong, inelastic, and nonconductive fiber, such as a meta-aramid or para-aramid that protects the integrity of the conductive wire during knitting. The conductive wire can be copper-clad stainless steel or copper wire is coated with polyurethane, and the nonconductive yarn can have no-drip and no-drip properties to allow ablation of the hybrid yarn to remove the conductive yarn and insulating coating on the wire such that the ablated region becomes externally conductive and suitable for making an electrical contact. The hybrid yarn can be bonded with nylon or similar polymer after twisting.

A device module (100) and method for connection to a textile fabric (50) with electrically conductive threads (51, 52) to provide a fabric layer assembly (150). The device module (100) comprises a flexible foil (10) and a thermoplastic layer (20) to enable a mechanical connection (M) between the flexible foil (10) and the textile fabric (50). The device module (100) has an outer circumference (C) comprising inward notches (N1,N2) configured as anchor points for respective conductive threads (51, 52) for holding and guiding the conductive threads (51,52) over and in contact with the respective conductive areas (11, 12) for providing the respective electrical connections (E1,E2) while the mechanical connection (M) by the thermoplastic layer (20) is established.

A fiber composite component with integrated active electromagnetic shielding includes a fiber composite layer having reinforcing fibers, and an electric conductor, which extends on the fiber composite layer along the fiber composite layer and produces an electromagnetic field during operation, wherein a proportion of the reinforcing fibers is designed as conduction fibers, which are arranged to follow the electric conductor within the fiber composite layer and are designed to produce an opposing electromagnetic field during operation which attenuates the electromagnetic field of the electric conductor.
