Alpenperser 2000 swatches
by Hannah Perner-Wilson, 2015

It’s the year 2000, we clad ourselves in the highest tech clothing that cools us when we’re hot, heats us when we’re cold and makes us smell nice always. But even high tech clothing becomes old, gets passed down and donated until nobody will wear it, and then what? Nothing all that new; Our worn-out futuristic garments get woven into electronic rag rugs.

Weaving rugs from scrap fabrics has tradition in Austria and they are known as Fleckerlteppiche or Alpenperser. The Alpenperser2000 is a rag rug woven from combined strips of conductive and non-conductive fabrics. Not to waste the electrical capabilities of these high-tech “scraps”, the weaving pattern is constructed to make up a series of isolated conductors and piezoresistive areas. This construction allows the rugs to be turned into floor-bound sensors capeable of capacitive, resistive and piezoresistive sensing.

Technique:
Weaving strips of cut fabric in a plain weave to create colourful conductive carpets that are capable of capacitive and piezoresistive sensing. Instead of sandwiching the piezoresistive material with the conductors on-top and on-bottom of the pressure application direction, this design sandwiches the piezoresistive material (stretchy Eeonyx) with the conductors on either side of silverized nylon conductive fabric strips.
