## Abstract

A cable and methods of making cables are disclosed. In at least one embodiment, a method for making a cable includes introducing a conductive material onto a sheet including a heat-shrink material. The method includes compressing a first portion of the sheet onto a second portion of the sheet to form a sheath having an interior volume, where the conductive material is disposed in the interior volume. In at least one embodiment, a cable includes a sheath including a heat-shrink material. The cable includes an interior volume including a conductive material including a conductive carbon material.
