    Weaving Conductive Fabric


    Commercially available conductive fabrics are mostly evenly coated basic woven and knit structures. There is nothing fancy, distinct or particularity interesting about their aesthetic appeal. They are metallic, shiny and uniform. What if you could weave your own conductive fabrics. For one you could tailor the electrical properties of the fabric to your own designs, […]

    Fabric Speakers


    Inspired by Marcelo Coehlo’s paper speaker and Vincent Leclerc’s Accouphene textile speaker, these paper and fabric speakers are made by running 5-9V sound amplified signal through a very conductive coil in close proximity to a magnet. Unlike most speakers that have the wire coil wrapped cylindrically and placed around the magnet, here the coil is […]
