Schoeller Wool

Schoeller (based in Austria) offers some really nice conductive yarns. We have received samples of their Nm %Inox steel fiber and %PET yarns which all have interesting resistive properties that change (decrease) when stretched or pressured. All yarns are great for both hand and machine knitting. We are currently using them to make stretch and pressure sensors as well as crochet potentiometers. Nm 10/3 is a nice thick yarn, their Nm 50/2 yarns are much thinner and have slightly higher resistance and can be torn easily, but when knitted together with another yarn are very stable sensors.

Wera Tech

Wera is a New Zealand based company that produces conductive yarn that is pretty much identical to the Schoeller yarn. They also use Inox steel fiber, but mixed with Laine instead of Polyester - Nm 20/2 70% Laine, 30% Inox. The other sample i have from them is called Tex 100/2 BL Trial, SH Undyed.
