Lars,
we have done all the things you need but not in one system. You could look
at our webpage
http://www.bmtp.akh-wien.ac.at/bmt/17mesi/17mesi_e.htm
for a totally implantable measurement system
and
http://www.bmtp.akh-wien.ac.at/bmt/sauest1/hfopti.htm
for our work about transcutaneous power transfer, which has been
finished by now.
to be more specific in any advice you would have to support more details,
for example what you mean by long distance.
Grretings
Stefan
