A conductive textile is a fabric which can conduct electricity. Conductive textiles known as lamé are made with guipé thread or yarn that is conductive because it is composed of metallic fibers wrapped around a non-metallic core or has a metallic coating. A different way of achieving conductivity is to weave metallic strands into the textile.
The simplest way is to incorporate metal wires or wire meshes into fabrics. Another approach is to use metalized yarns. In staple yarns, it is possible to spin short strands of regular yarns with metal yarns. Electrically conducting yarns may be made of a central metal strand with regular yarn woven around it.
Smart textile fabric can be made from materials ranging from traditional cotton, polyester, and nylon, to advanced Kevlar with integrated functionalities. At present, however, fabrics with electrical conductivity are of interest. [20]
Even at a very low level of doping (< 1%), electrical conductivity increases several orders of magnitude up to values of around 0.1 S/cm. Subsequent doping of the conducting polymers will result in a saturation of the conductivity at values around 0.1–10 kS/cm (10–1000 S/m) for different polymers.
Metallic fibers are manufactured fibers composed of metal, metallic alloys, plastic-coated metal, metal-coated plastic, or a core completely covered by metal. [ 1 ] Having their origin in textile and clothing applications, gold and silver fibers have been used since ancient times as yarns for fabric decoration.
The electrical conductivity of silver is 106% of that of annealed copper on the IACS scale, and the electrical resistivity of silver = 15.9 nΩ•m at 20 °C. [ 14 ] [ 15 ] The high cost of silver combined with its low tensile strength limits its use to special applications, such as joint plating and sliding contact surfaces, and plating for ...

Gold-lamé and emerald royal boudoir gown from the film Cleopatra. Lamé (/ l ɑː ˈ m eɪ / lah-MAY; French:) is a type of fabric woven or knit [1] with threads made of metallic fiber wrapped around natural or synthetic fibers like silk, nylon, or spandex for added strength and stretch.
