Currently various parts used in the automotive and aircraft industries incorporate printed circuit boards into plastic components by adding punched and bent metal sheets to the plastic parts in a complex and expensive process. Plastic conductors would enable manufacturers to create these same parts in a single step, making them much cheaper to produce. The lack of metal would also make the resulting parts much lighter.
In addition to potential benefits to the aircraft industry, car manufacturers could replace expensive metal parts with this new material. For example, most cars include punched metal sheets fitted inside plastic headlight housings in order to illuminate the light. The headlight housings could be replaced entirely with the new conductive material, eliminating the second piece entirely without impeding headlight function.
