A motor-vehicle component, such as for example a fuel tank, or a pipe for the supply of fuel to the engine of the motor vehicle, or a motor-vehicle seat, or the bumper, has a structure at least partially made up of polymeric nanocomposite material containing carbon nanotubes. Associated to the structure are two electrical terminals, and carbon nanotubes are arranged so as to create a continuous electrical connection between said terminals. Electronic control and processing means are connected to said terminals in such a way as to detect the variation in the electrical resistance of the structure made of polymeric nanocomposite material containing carbon nanotubes as its strain varies. It is thus possible, for example, to obtain a signal indicating the degree of filling of the tank, or the pressure existing within the pipe, or the presence of an occupant on the seat or his posture, or pressures and/or impact to which the bumper is subjected.
