A transmission cable may include a conductor core, an insulator layer surrounding the conductor core, and a shielding layer surrounding the insulator layer, wherein the shielding layer includes a carbon nanotube sheet material.

A structural health management system may include a structural health management apparatus including a carbon nanotube element configured to generate an electrical output in response to a deformation of the carbon nanotube element, a piezoelectric element configured to actuate in response to an electrical voltage applied to the piezoelectric element, electrode elements coupled to the carbon nanotube element and the piezoelectric element, and a controller communicatively coupled to the structural health management apparatus, wherein the controller is configured to convert the electrical output into data representing a measurement value of a structural abnormality and to initiate application of the electrical voltage to the piezoelectric element to counter the structural abnormality upon the measurement value being equal to or greater than a predetermined threshold value.
