Measuring stretch forces isn't easy - unless you have some conductive rubber cord! This cord is 2mm diameter, and 1 meter long, made of carbon-black impregnated rubber. Usually this material is used for EMF gasketing, but its also very fun to play with.
This is 30 feet of conductive thread spun from stainless steel fiber and wound on a plastic bobbin. Use it to sew up all of your e-textile projects.
You can easily solder to it, and the tape itself can carry current just like a wire.
