Hi,

Years ago, I proposed a very simple solution to the problem of recharging 
pacemaker batteries, on this list:- Use a
lossy air core transformer to recharge the battery as required. Sure it 
wouldn't be efficient, but it would obviate any
requirement for surgery, and could be done by simply holding a coil against the 
chest for a short period.
With a little imagination, the same "communications channel" (i.e. the magnetic 
field), could be used to transfer
information as well.
