A stretchable conductor includes a substrate with a first major surface and an elongate wire, wherein the substrate is an elastomeric material, the elongate wire is on the first major surface of the substrate, the wire includes a first end and a second end, and further includes at least one arcuate region between the first end and the second end. At least one portion of the arcuate region of the wire in the region has a first surface area portion embedded in the surface of the substrate and a second surface area portion unembedded on the substrate and exposed in an amount sufficient to render at least an area of the substrate in the region electrically conductive. The unembedded second surface portion of the arcuate region may lie above or below a plane of the substrate. Additionally, different methods of preparing said stretchable conductor are disclosed. Composite articles including said stretchable conductor in durable electrical contact with a conductive fabric are also disclosed.

A hand-wearable device includes an elastic sheet including a first elastic layer and a second elastic layer facing each other; a sensor unit formed by printing a predetermined conductive liquid metal between the first elastic layer and the second elastic layer; a wire unit extending from the sensor unit and electrically connected to the sensor unit; an electrode substrate formed on one side of the wire unit and spaced apart from the wire unit by a predetermined distance; and a connection electrode formed by printing a predetermined conductive liquid metal between the wire unit and the electrode substrate.

The exemplified systems and methods provide an extension cord system having a cord that is configured to slidably guide a movable plug carriage having conventional plug receptacle. In some embodiments, the movable plug carriage is configured with pierce-able conductors that can be inserted and retracted from a sealed skin of the cord. In other embodiments, the sealed skin can be fastened and unfastened by the movable plug carriage as the movable plug carriage moves over the cord. In yet other embodiments, the movable plug carriage is attachable and detachable from the cord.

The present application provides a conductive film, a manufacturing method of the conductive film, and a display device. The present application prevents refracted light by using a first metal layer to fully cover a second metal layer of a middle layer, thereby fundamentally solving black level stripes caused by lateral etching of the second metal layer.

An MOCVD system fabricates high quality superconductor tapes with variable thicknesses. The MOCVD system can include a gas flow chamber between two parallel channels in a housing. A substrate tape is heated and then passed through the MOCVD housing such that the gas flow is perpendicular to the tape's surface. Precursors are injected into the gas flow for deposition on the substrate tape. In this way, superconductor tapes can be fabricated with variable thicknesses, uniform precursor deposition, and high critical current densities.
