The number of application fields of micro systems and microelectronic components are increasing continuously. International fairs clearly show smaller and compact circuits on foil substrates. Especially the sensoric
and actuatoric sensor systems become more flexible . However, non
rigid and extremely loadable and bendable may only be manufactured
from textiles. The galvanic and electrochemical finishing of textiles is
one way to build textile based micro systems. A concept for the production of electrically highly conductive, functionalized and interactive yarns is proposed. The first step of the concept, the highly conducting yarns, are already transferred into an industrialized production and is commercially available. Silver coated polyamide yarns are already on the market since the end of the seventies. Till now the applications have been limited on the use of their anti-electrostatic and anti-microbic properties. The drawbacks of the yarns can be overcome by an electro-chemical treatment to increase the metal layer, to create multi layer systems or functional top layers by anodization and other electrochemical techniques like the electro-polymeris-ation and electrodeposition of paint. So treated yarns can be processed by any textile technology.
