Can Modifying the Flexiforce Drive Circuit Enhance Sensor Performance?

[prescott2006]

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?

Where did you get that circuit from? A couple things look weird about it, obviously. What are the I/O characteristics of that opamp?

I get it from Flexiforce data-sheet, that is their recommended excitation circuit. What are the things that look weird? What do you mean by I/O characteristic of the opamp?
