Carbon nanotube-based fibers have greater capacity to carry electrical current than copper cables of the same mass, according to new research.

A series of tests at Rice University showed the wet-spun carbon nanotube fiber still handily beat copper, carrying up to four times as much current as a copper wire of the same mass.

The nanotube-based cables are an ideal platform for lightweight power transmission in systems where weight is a significant factor, like aerospace applications.

The team plans to further investigate and explore the fiber’s multifunctional aspects, including flexible optoelectronic device applications.
