Description
Measures stretch force easily using this conductive rubber cord! This kit contains approximately 1 meter of conductive cord, 2 alligator clips and a resistor. The cord can be stretched between 50 and 70% longer and its resistance will change accordingly!
In a ‘relaxed’ state, the resistance is about 350 ohms per inch. As you pull on it, the resistance increases (the particles get further apart). As you stretch it out, the resistance increases. So lets say you have a 6″ piece – thats about 2.1K ohms. Stretch it to 10″ long and now it is 10″/6″*2.1K = 3.5 Kohms.
Once the force is released, the rubber will shrink back, although its not very ‘fast’ and it takes a minute or two to revert to its original length. It’s not a true linear sensor, and the resistance may vary from batch to batch, so we consider it a way to measure stretching motion but isn’t really precise
