1. A machine-knittable hybrid yarn, comprising:
one or more electrically non-conductive yarns; and
two or more electrically conductive wires wrapped around the electrically non-conductive yarns, the electrically conductive wires have an exterior layer of an insulating material,
wherein the electrically non-conductive yarns comprise a majority fraction of an overall cross-section of the hybrid yarn,
wherein the two or more electrically conductive wires are wrapped around the one or more electrically non-conductive yarns at between 1 and 15 twists per inch, and
wherein the one or more electrically non-conductive yarns are 1500 denier or finer.
