While the fibers they tested were cut into centimeter lengths, Komatsu said there’s no reason devices can’t make use of the excellent nanotube fibers from the Pasquali lab that are spooled in continuous measurements. “No matter where you measure them, they have the same very high electrical conductivity,” she said. “The piece I measured was small only because my setup isn’t capable of measuring 50 meters of fiber.”

Electrochemical capacitors (ECs) have only recently been considered as an alternative power source for telemetry sensors of drilling equipment for geothermal or oil and gas exploration. The lifecycle analysis and modeling of ECs are underrepresented in literature in comparison to other storage devices e.g. Li-ion batteries.
