I always wondered if nerves sent signals to our muscles, if someone lost a leg or an arm, is it theoretically possible to attach someone's nerves to machinery and control it like a limb?
There are already artificial limbs that work on that principle. Electrodes on the skin pick up signals from muscles in the limb stump or elsewhere on the body, and those are used to drive actuators in the limb. The technology is fairly basic at the moment - just a few movements can be controlled - but it will probably get better. It would be nice if we could attach directly to the nerve bundles in the arm or leg because there are thousands of motor nerves in there. The big problems are infection, stopping the nerve dying, and the body rejecting the electrodes.
yes i have heard some work is being done with that
