Scientists have found a way to create bio-batteries, similar to the electrocytic cells of electric eels and other such electric animals. The idea behind this is to power artificial limbs and internal machinery, but of course, the idea could be taken a step further and into the creation of “wetware”, or cybernetic implants. Mind you, according to the article:
There’s a long way between the drawing board and the cyber-implant in the world of biotechnology, at least for those of us outside of Marvel, and several “How do we actually build this?” questions have to be answered.
Ok, so it’s not quite reality yet, but the fact that there are blueprints means that at least it’s a big step toward seeing this come to light.
