Resonant Energy Transfer.

This article on wireless energy transfer seems worth a look. Depending on how strongly this effect works in real life, it may be a viable solution for powering smart-dust sensor systems.

Wireless energy transfer has existed for years. The major problem, though, seems to be that reverting the energy in a speeding bullet to usable energy is a bit of a pain... literally :-p

The problem is that any body part you did happen to have with the right resonant frequency, would 'splode.

Clearly we would need some public safety laws restricting the shapes and compositions of people's body parts.
