Hi I have a fabric that is knitted with conductive thread. When the fabric is stretched the resistance changes. My problem is that the resistance changes very little, for instance 5ohms. Is there a way to amplify the change in resistance so that 0-5ohms will be more like 0-100ohms?
Here is an example of a fabric. I was using a microcontroller to deal with scaling the resistance here, but I'd prefer an all-analog solution to save on cost.
