Claim:
1. A bus bar having a longitudinal axis and comprising: a coating having a plurality of memory metal wires configured to contract in response to an increase in temperature that are embedded in the coating to for a memory metal internal framework; an electrically conductive material applied to the memory metal internal framework through an additive manufacturing technique and configured to expand in response to the increase in temperature such that the contraction of the wires at least partially offsets the expansion of the electrically conductive material, the memory metal internal framework and the electrically conductive material forming a substrate of the busbar; and a solder pad directly added to a surface of the electrically conductive, material via additive manufacturing, wherein the plurality of wires are oriented along the longitudinal axis to exploit contraction in the longitudinal direction, and. the composition of the memory metal internal framework and the electrically conductive material comprise a substantially net zero coefficient of thermal expansion in response to current flowing through the bus bar.
