Could 'nerves of steel' guide sensory signals?

This article makes assumptions of the consequences of having coaxial steel cables for nerves. It is found that if a person would have coaxial steel cables instead of axons, the body would have to find a way to impose an initial potential of about 90 mV onto the beginning of this axon since the signal is now passed on passively instead of actively. This signal is however not seriously damped within the cable. This nerve would however be able to handle impulses of a higher frequency at a higher speed, allowing one to have a higher maximally ‘feelable’ intensity of sensations
