Get me out of town is what fireball said
What is electricity? It’s moving electrons.
Every living thing moves electrons around, not just in nerves but also in metabolism (oxidize one thing, reduce another).
Is it possible to use this metabolic electricity to communicate with man-made devices? If you could, you might be able to make very sensitive biosensors, or even use bacteria to charge your batteries.
The first question you would need to address is whether you could get the electrons generated by metabolism out to the surface of the cell where they could be captured by a metal electrode.
Several species of bacteria do this naturally. One of the best-studied of these is Shewanella oneidensis, and the reason it needs to move electrons to the surface of the cell is so that it can use metal oxides as electron acceptors when there’s no oxygen around: in effect, these bacteria “breathe” metal. Lots of applications have been suggested based on this unusual property, including uses in bioremediation.
