Does anyone have a suggestion on how to build or where to buy
a sensor for a feedback loop which will detect the air/fluid or 
air/solid interface within 0.001mm?  The device must determine 
the thickness of a very soft material, and be able to detect
the surface without deforming it.  For robotics, it would close
the "caliper" until it "touched", then note the thickness, and
procede with the next step.  Any suggetions appreciated.
