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?

Yes ,but to what end.

I just want to get the best excitation circuit to drive the sensor. Can you explain why they would improve the sensor's performance?
