    Attached is the Flexiforce drive circuit. I would like to ask whether I can improve improve the performance of Flexiforce in term of linearity, hysteresis, repeatability, or whatsoever other parameter by change the drive circuit to Wheatstone bridge or instrumentation amplifier?

    The circuit itself has no real use, until it is married with the physical component being gauged. The attachment methodology and the supporting substrate have everything to do with the items you've mentioned. With that being said, things can be done to the circuit, but is it right or wrong when applied to the application is but a wild guess.

    These parameters have more to do with the Flexiforce device than with the op amp.

    Is there some noted deficiency you are trying to correct?
