Among nanomaterials, carbon-based nanoparticles such as carbon nanotubes and graphene have shown promising results, but they suffer from relatively low electrical conductivity,
Other groups have made similar supercapacitors using carbon nanotubes or other materials, but the niobium yarns are stronger and 100 times more conductive.
Overall, niobium-based supercapacitors can store up to five times as much power in a given volume as carbon nanotube versions.
and carbon nanotubes that could be woven into clothing. At the time these fibers were said to obtain the highest volumetric energy density reported for carbon-based microscale supercapacitors (6. 3 microwatt-hours per cubic millimeter,
However carbon nanotubes are still expensive not to mention the fact that there is still some debate about their possible toxicity.
The fiber, made from sheets of carbon nanotubes wrapped around a rubber core, can be stretched to 14 times its original length
In research published in the journal Science, the team describes how they devised a method for wrapping electrically conductive sheets of carbon nanotubes around the rubber core in such a way that the fiber's resistance doesn change when stretched,
but its conductivity increases. e make the inelastic carbon nanotube sheaths of our sheath-core fibers super stretchable by modulating large buckles with small buckles,
and then another carbon nanotube sheath to create strain sensors and artificial muscles. In this setup, the buckled nanotube sheets act as electrodes

#Carbon nanotube finding could lead to flexible electronics with longer battery life Led by materials science Associate professor Michael Arnold
Carbon nanotubes are very strong and very flexible so they could also be used to make flexible displays
Carbon nanotubes are single atomic sheets of carbon rolled up into a tube. As some of the best electrical conductors ever discovered carbon nanotubes have long been recognized as a promising material for next-generation transistors
which are semiconductor devices that can act like an on-off switch for current or amplify current. This forms the foundation of an electronic device.
However researchers have struggled to isolate purely semiconducting carbon nanotubes which are crucial because metallic nanotube impurities act like copper wires and short the device.
Building on more than two decades of carbon nanotube research in the field the UW-Madison team drew on cutting-edge technologies that use polymers to selectively sort out the semiconducting nanotubes achieving a solution of ultra-high-purity semiconducting carbon nanotubes.
In that technique researchers exploited a self-assembly phenomenon triggered by rapidly evaporating a carbon nanotube solution.
