Hannah Perner-Wilson has been experimenting with various configurations of crochet sensors. The steel fibers in the conductive yarn change resistance when they are smushed or pulled, which can be read on a multimeter or fed to a microcontroller for controlling any number of circutis. Using the nuckle-positioned one, you could control a video game just by bending your fingers. Or maybe it senses that you’re squeezing your baseball bat too hard, and encourages you to loosen your grip. This conductive yarn has some interesting implications for wearable electronics, I can’t wait to see where it goes!

    So where would one find this conductive yarn? I would love to light up the runway with some fashion made of this.
