Fine copper-brown thread wound in dense even rows on a white plastic bobbin, a loose end trailing across the bottom.
  • A close view of the wound thread, its metallic copper strands catching the light in bright bands and lying in tight parallel rows.

Blank copper conductive thread is a flexible fiber that conducts electricity, while handling like regular sewing thread. It enables the integration of electrical pathways into fabric, making it ideal for sewn or soft circuits and e-textiles. This sample was made in Germany, hence the German kupfer.
