Alternative contacting
To avoid the need for graphite tunneling contacts which need quite some surface and dissipate some power a reziprocating drive could be electrically connected with flexing nanotube connections. The flex must be low enough to not disturb the electric properties (conductivity) of the nabotube too much.
