We report a highly stable electrical conductance of a compact and well-oriented carbon nanotube yarn under tensile strain. The gauge factor of the yarn was found
to be extremely small of approximately 0.15 thanks to the
improvements in the dry spinning process, includingmultiweb
spinning and heat treatment. The threshold strain εs, below which the yarn retains its electrical conductance stability, has also been determined to be approximately
15 × 103 ppm. Owing to its highly stable resistance under
mechanical strain, the yarn has a good potential as a wiring
material for niche applications,where lightweight and resistance stability are required.
