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!
