A semiconductor module includes a printed circuit board including an integrated circuit chip, connecting terminals at an edge of the printed circuit board, and signal lines respectively connecting electrical connection pads of the integrated circuit chip to the connecting terminals. The connecting terminals are plated using via-holes of the printed circuit board respectively connected to the signal lines.

An electronic device includes a first substrate having bendability, a second substrate configured to include a first electrode and provided over the first substrate, a third substrate configured to include a second electrode and provided over the first substrate with a space from the second substrate, a first electronic component configured to be electrically coupled to the first electrode and provided over the second substrate, a second electronic component configured to be electrically coupled to the second electrode and provided over the third substrate, and a wiring configured to include a plurality of conductive thread-shaped members sewn into the first substrate in an extensible and contractible state so as to be electrically coupled the first electrode to the second electrode.

A flexible device includes a first conductive pattern, a second conductive pattern, and a dielectric layer. The first conductive pattern includes a first sliding contact portion and a first extension portion. The second conductive pattern includes a second sliding contact portion overlapping with the first sliding contact portion and the second conductive pattern includes a second extension portion. The second sliding contact portion is in contact with the first sliding contact portion and is movable on the first sliding contact portion for a sliding motion. The first and second conductive patterns are embedded in the dielectric layer.

Systems, apparatuses, and/or methods to manufacture and/or implement a sensor film, a composite electrode, and/or a computing device such as a flexible device. The sensor film may include a random network of metal lines and graphene interconnecting the metal lines. The composite electrode may be formed from the sensor film. In addition, the composite electrode may include a first portion including a metal layer in a graphene layer, wherein the metal layer is randomly located in the graphene layer, and a second portion excluding the metal layer and including the graphene layer. The sensor film may be patterned to include any composite electrode configuration, such as an antenna electrode configuration, a touch electrode configuration, and so on. Thus, the flexible device may include a flexible touch screen.
