Electronically conductive cellulose-yarn developed by WWSC researchers
Researchers from WWSC at Chalmer and KTH have together with researchers from Sweden, Finland and South Korea developed conducting cellulose yarns that can be used for making electronic textiles. The developed textile yarns displayed record-high bulk conductivity of 36 Scm–1 and could be washed multiple times.

The yarns were produced by a roll-to-roll coating process with an ink based on the biocompatible PEDOT:PSS and could be used in a household sewing machine. The findings were recently published in ACS Applied Materials & Interfaces.

“This cellulose thread could lead to garments with built-in electronic, smart functions, made from non-toxic, renewable and natural materials,” says Sozan Darabi, PhD student in WWSC in professor Christan Müllerss group to
