Silverthread Conductive Thread
This is an economical, highly conductive thread for use in hand or machine sewing. This synthetic material feels and behaves like conventional cotton but is made up of over 100 strands each with a nano-coating of silver.
It has an electrical resistance of just 4 Ω per 100mm – meaning that just a single thread can be used in place of wires in electrical circuits for LEDs etc. In experiments, we have even run electric motors using up to a metre of Silverthread as a substitute for normal metal wiring. This material can be used in garments and soft products as a woven-in conductor and to secure small circuit boards and wire components to fabrics.
