alright well here me out, look at the leg. people are researching, and even researching this at my school, polymers that conduct electricity. my brother knows more about them but the idea is that copper is expensive and it's hard to get. it's way easier to polymerize something that conducts electricity than to get copper. or it will be once someone figures it out. so then you won't need to get copper to use for electrical wiring.
thats what they want to use it for, but i could also be an artificial nerve network. i suppose minus the fact it's one long continuos chain whereas the actual nervous system is not. there's probably a way around it though.
