3D printed electric eel organs could power tomorrow's implantables for human and robots

A team of international researchers have turned to an unlikely yet ingenious source of electric power that runs on only salt and water: the common electric eel. For millennia, the electrophorus electricus, a knife-fish widely known as the electric eel, has been capable of zapping its prey through a sophisticated electrical system that can generate up to 600V and 100W of power.
