Given the particulate nature of carbon I'd be surprised if you could get 2 micron accuracy from a carbon resistance track.

Is it necessary to use resistance as a measurement basis?
The device shown here has the required measurement accuracy, if it could somehow be adapted:
LVDT instrument
They are commercially available.
