Transducers/calibrations (FSR'S)

[B7gw000__ron Turchyniak]

Hi all

I am presently using the EDG gait analysis system
which uses discrete transducers to measure pressures on the plantar
aspects of the feet.

I would like to know if anyone knows what exactly is involved in
calibrating these transducers (or similar ones) ?
NB:
The transducers are force sensitive resistors that have a hyperbolic
resistance pressure relationship.

The manufacturer (Langer Biomechanics) says that their new software
performs sensor calibrations, I would like to know what type (how)
of calibration is performed by the software ?

I encourage any general comments with respect to these types of
transducers, I am not familiar with the engineering that goes
into these transducers.
..are these FSR's temperature sensitive..
. or affected by shear or bending .. ?

Thanks

Ron
