Hey /sci/.

I'm new to this board but I've thought of something.

So I've been looking at some videos on bionic/prosthetic arms and, they're all either controlled by buttons or really really slow.

Let's say someone's hand or arm was blown up (not off) but the remains of the nerves were still there, then could we somehow implant them in the prosthetic limb and provide instant reaction as if is were real?

I mean of course this would be easier with just a hand,

If any smart people want to make me look like a fool, go ahead, I'm just putting a point across

i've been wondering how close we are to this
most of the brain-controlled stuff i've seen so far still has to learn the input, it would be amazing if we could just attach it to the relevant nerves and use the same impulses

As Far as I know this is usually the case, the prosthetic is connected to residual muscles and nerves through electric wiring where the potential is measured and then transcribed into motor function
Big problem with this is however that the wiring (which is a bunch of metal poked into your flesh) causes scar tissue to form and also destroys the nerves due to it being not very flexible. Thus after a while the prosthetic arm/leg doesn't work anymore.
One way to solve this would be to use conductor nets instead of pins. I can't give you a reference right now but I remember reading about a group of scientist that managed to create a conducting net out of carbon fiber. One of the big advantages was that it wasn't just not rejected, but that the nerves began to grow closer to it, increasing it's efficiency.

Really? Does the same thing happen with normal biohacking?

We could, except for the fact that current electrical nerve interfaces suck.
