Or just use piezoelectrics.  Draw power from the
body's movement; pulse off a transmission that can be
detected by satellites whenever enough energy has
been stored.  Which means someone seriously on the
move would be tracked more often than someone just
sitting still, waiting for the world to come by.
Possible issues with storing that much energy, but it
seems potentially doable, especially if the signal is
on a frequency normally kept empty.

Having been on both sides of that particular
situation, I always qualify those words, for instance
with "not possible using today's technology" or "I do
not see a way this could be done".
