Linear induction generator for subdermal circuits?

Loptr

Here is one for the electronics gurus. Think it may be possible to make a linear induction generator, like a Faraday flashlight, small enough to implant and still be large enough to trickle charge a battery or capacitor for low powered electronics? I'm thinking like this subdermal wristwatch of @S0lll0s .  Something implanted perpendicular to the arm's length so that most movements of the forearm, especially walking, would generate motion.  Thoughts?

we have already talked plenty about the pros and cons of such a system, read these links http://discuss.biohack.me/discussions/tagged/power

Thanks for the links! Guess I suck at searching before posting. I did try. XD
