Electrically conductive filaments are used in a wide variety of applications, for example, smart textiles and soft robotics. Filaments that conduct electricity required the transmission energy information, but up until now, most electrically fibers, wires offer low mechanical elongation. Therefore, they not well suited implementation into elastomeric composites worn close to human body have follow range movements. In order overcome this issue, presented study aims at development elastic...
