Abstract: One manner of producing more desirable clothing with electronic capabilities is to manufacture electronics, such as the charging wires or devices themselves, directly onto the textile materials. Textile materials generally do not support the manufacturing of electronic devices, in part because the surface of the textile is too rough for electronic devices or the processes used to manufacture electronic devices. An intermediate layer may be placed on the textile material to reduce the roughness of the surface of the textile material and provide other beneficial characteristics for the placement of electronic devices directly on the textile material.
