A sensor cable (10) for detecting and/or locating a deformation of the cable includes a conductive core (20), a dielectric layer (40), a controlled resistive layer (50), a piezoresistive layer (60), and an outer shield (70). Deformation of the cable (10) creates a change in resistance between the shield (70) and the controlled resistive layer (50), and also creates a piezoelectric-induced voltage between the conductive core (20) and the controlled resistive layer (50). The incidence and/or location of a deformation of the cable is deducible from electrical parameters, indicative of the change in resistance and the induced voltage, measured at one or both ends of the sensor cable.
