How to measure a small change in resistance?

[davidd31415]

I'm looking for a way to measure a small change in resistance (not
necessarily a small resistance, just a small change). Is there a
common configuration of a wheatstone bridge or some other circuit that
I should consider for this? It is not a problem if the measurement
ends up being a voltage which needs to be converted to a resistance or
something similar.

I'm looking at measuring less then 1 ohm changes in 2-4kohm
resistances.

Thanks!

sounds just like a strain guage, you could use the same ciruit for one,
should be many examples from google.
