Systems and devices for continuous, high-throughput production of electrically conductive yans, fibers or fabrics. In one embodiment, the system comprises a first process chamber for coating the yarn, fiber or fabric with an electrically conductive material and a second process chamber for encapsulating the electrically conductive yarn, fiber or fabric with an encapsulating material. In another embodiment, device for printing an encapsulated electrically conductive material on a yarn, fiber or fabric, includes print head(s) for coating and encapsulating a yarn, fiber or fabric.

Touch sensor technologies are provided. In some embodiments, a touch sensor device includes an array of conductive members. The touch sensor device also includes a first routing trace electrically coupled to a first conductive member of the array of conductive members. The touch sensor device also includes a second routing trace electrically coupled to a second conductive member of the array of conductive member. The first and second routing traces extend to a connector integrated into the touch sensor device. The touch sensor device further includes a resistor that electrically couples the first routing trace and the second routing trace. A third conductive member of the array of conductive members is placed between the first and second conductive members. By incorporating a resistor, density of conductive members (sense lines and/or drive lines) can be increased without increasing density of routing traces to the connector.

The present disclosure relates to a triboresistive touch sensor capable of generating electric power by electrification and electrostatic induction, and thus sensing a touch position without a grid.

A conductive polymer composition containing: a composite containing a π-conjugated polymer (A) and a polymer (B) shown by the following general formula (2); H.sub.2O (D) for dispersing the composite; and a water-soluble organic solvent (C). This provides a composition which has favorable filterability and film formability, and which is capable of relieving acidity and forming a conductive film with high transparency. Moreover, since the H.sub.2O dispersion of the conductive polymer compound is mixed with an organic solvent, the surface tension and the contact angle are so low that leveling property on a substrate is imparted. The composition is usable in droplet-coating methods. Since an organic solvent having a higher boiling point than H.sub.2O is used as the organic solvent, the composition can avoid solid content precipitation around a nozzle and solid content precipitation due to drying between ejecting the liquid material from a nozzle tip and landing on a substrate.
