Measuring Stress with Sensors

datamodelingstrain-gage

I wanted to ask a few questions in the hoped that someone can advise me.

Basically I wish to use a sensor which will be attached to a large piece of fabric, I would then like to use the data from the sensor to inform me about the stress-strain relationship, create and predict models and compare with any existing models.

Any advise, links or research to read into would be incredibly helpful!

I would recommend using a resistive strain gauge, a Wheatstone bridge, and an op-amp-based signal conditioning circuit. The values and setup will likely differ depending on the sensor you use, but here's the general circuit:

Hopefully this points you in the right direction. Keep searching google and you will find more information.
