Description: This is a conductive knit fabric for use in e-textiles. It is silver-plated nylon that is stretchy in one direction. It is highly conductive with a surface resistivity of < 1 ohm/sq. This is a great add-on to any LilyPad project. Medtex 180 Ag Nylon single directional stretch. It is a bit thicker than the Medtex 130.

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.

Features:

  • It's conductive!
  • Easily sew electronic features into your next project
  • Great for use with the LilyPad

Dimensions: 12 x 13" (304.8 x 330.2 mm)

  • A question I have is … if I took a 2" x 2" piece of this material and poked a hole in the material would I see resistance change that could be measured by a ADC?

    Thanks

  • Has anyone tried using this thing as a heating element?

  • Does anyone know why the resistance of the square reduces when stretched? I think it has something to do with tightening of the weave but Im not sure. It is also counter to the resistance equation of materials in regards to length and cross sectional area.

    • Actually it works with the resistance equation of materials, as you are stretching the media the cross sectional area will shrink, the degree to which it shrinks is determined by the poisson’s ratio of the material. In addition to that you are lengthening the fabric, which would also cause an increase in resistance. In essence stretching the fabric is making a longer resister with smaller surface area, giving you maximum resistance.

  • Will this work for as a Faraday bag?

    Do you got some, just wrap you phone in it and see if you have service… Then let me know.

  • After using MedTex130 for my Stylus Socks for iPad, I’m now testing MedTex180. Initial tests are very promising; less stretch, but more grip! Assembly is still a challenge though. More at Etsy:
