The accuracy of Force Sensitive Resistors (FSRs)
simulate this circuit &ndash; Schematic created using CircuitLab
300mV deflection at 2/3 FSR rating for load from 2/3 to 1 x FSR rating ?

Static load is probably quasi static, so dynamic touch will be problematic so DC tracking by AC amplification
Some problems with OEM specs at 10k expecting 2.5V at 50% FSR but only seeing 20% on left.

batch to batch variations may need a pot anyways.

Conclusion

possible if static load is true static.

undefined problems with this approach.
