Carbon
nanotube based nanoposition
sensors
Prototypes
of individual carbon-nanotube-based nanoposition sensors for detecting approaching, touching,
and sliding positions are proposed on the bases of the interelectrodedistance-based
field emission current change of a nanotube emitter
and the resistance change caused by sliding motion of nanotube
on an Au substrate.

sensor, (b)Relation of tinterelectrode distance and
emission current (c)Relation between the tip position of a nanotube
and the current under 10V constant bias.
