Here we have some conductive ribbon. Essentially, it’s a fabric with 3 conductors woven into the ribbon. It measures roughly 0.2" wide and 0.03" thick. You will get a 1 yard (~3 foot long) section of ribbon. It has very little (negligible) resistance to it. The material is 68% tinsel and 32% polyester.
Since it has 3 discrete conductors in it, you can transmit power, ground, and signal with a single ribbon! It’s relatively flexible and durable. As long as your iron isn’t too hot, it solders easily and makes for a good addition to any wearable electronics project.
