It is possible. You'd have to read up on series resonant power transfer
and stuff like that. IIRC there was an experiment outlined somewhere on
the web where they did that on a road in New Zealand. They could move
illuminated lane boundary markers around by just sticking them onto the
road surface anywhere there was inductive power, and they'd light up.

BUT: This can violate agency limits for RF emissions and could create a
hazard for people, especially those with pace makers. Or imagine an
ankle bracelet that slowly burns itself into the skin.
