Subdermal bone conduction headphones?
So, I've been thinking about the modifications I want, and a magnet in the finger doesn't appeal too much to me. I have some ideas for magnets, but there is one idea that's is much more interesting and nove to mel: subdermal bone conduction headphones. I've done a little thinking on it but so far everything is very theoretical.
So far it seems like my best bet would be to use some form of flexing piezoelectric element, of which I can harvest a simple one from a Radio Shack buzzer. Then bioproof it, figure out a way to power it, and then supply it with signal.
But the problem is I want the connection point to be closer to my pocket, where I'm more likely to keep a music player than my skull. That means in addition to some way to keep the buzzer bioproofed and attached to the skull, I need wiring of some sort.
So basically, I'm just wondering if anyone's done any work on something like this. Has anyone dealt with anchoring stuff to the skeleton? My layman knowledge suggests that something like one of those hammer-on wooden beam connectors for a skull, with small holes in the metal stickout prongs that the bone could grow through should be sufficient and not too difficult to make out of biocompatible metals. But I'm not sure. And I'm not sure how to get the signal down my body, from each ear. I need to be able to carry a fair amount of power back and forth.
Any ideas or similar work?
