This is a conductive knit fabric for use in e-textiles. It is silver-plated nylon that is stretchy in both directions. It is highly conductive with a surface resistivity of < 1 ohm/sq. This is a great add-on to any LilyPad project. Medtex 130 Ag Nylon stretch. It is a bit thinner than our Medtex 180.
Notice:If you aren't sure what to do with conductive fabric, you have to check out the Wearable Toy Piano, as well as some of the other cool Instructables.
