Researchers at the Electronics Department and the Wearable Computing Laboratory at the ETH in<br />
Zürich produced a plain woven textile structure consisting of polyester yarns that are twisted with one<br />
copper thread.<br />

They examined different woven fabric structures to be used as textile transmission lines in wearable<br />
computing applications. They altered the structure by inserting the copper fibre either in one or two<br />
directions and by different yarn finenesses [25].<br />
Bekitherm® by Bekaert Fibre Technologies is a woven fabric, a knitted fabric or a needle felt<br />
consisting of 100 % metal fibres or of a mixture of metal fibres and a natural or a synthetic fibre. It is<br />
used in the production process of complex glass forms (car windows, bottles, TV tubes) and<br />
saucepans from stainless steel. It is also incorporated in plane engines to protect components against<br />
the heat and the vibrations of the engine block [10].<br />
The Danish company Chr. Dalsgaard Project Development ApS works with the development of<br />
weaving electronics into fabrics, electronic conductors in clothing, operating panels in textiles (soft<br />
keyboards, displays etc.) and micro-sensors. The company serves predominantly knowledge in the<br />
field of electronic textiles and works through joint ventures with textile companies. They developed, for<br />
instance, conductive ribbons for different purposes, such as loudspeakers and microphones. The<br />
conductive yarn they use is a copper thread, plated with a silver layer and coated with polyester [26].<br />
