Can I charge electricity into my titanium prosthetics?

Asked by Jeenyus (7points) June 15th, 2010

I have titanium plates and screws implanted from and open reduction, internal fixation surgery. Can it hold electricity and possibly repulse it?

Here is a chart showing the different electrical properties of different metals. It appears, if I’m reading it correctly, that it’s not the best conductor of electricity. Much less than copper, about the same as stainless steel. Also, I’m not sure than any metal actually “holds” electricity without a constant power source. But dude… if you try this and live to tell the tale, you must PM me.

I have a teeny titanium prosthesis (stapedectomy) in my ear. It replaces the stapes bone, which I fractured when I took a bad fall down some steps.

The stapes bone is the smallest one (1/10 ”) in the body. I do not have current running thru it.

OTOH, it did not improve my lost hearing.

Metal conducts electricity, it does not generate a potential difference like a battery by itself. A metal body can “hold” a static charge on its surface if it is isolated from ground. Seeing as the plates and screws are in contact with your bodily fluids, it won’t charge up relative to your body.

Electrochemistry and corrosion reading coming back to me… it’s more complicated than I made out at first. The classic battery is lead sheets in sulfuric acid. (The body tends to be bit acidic, so…) But the deal with titanium is that it forms a oxide film in aggressive environments that isn’t porous and adheres well to the metal rather than flaking off like rust on steel.
