A method for detecting and measuring a braking force and/or a braking torque deriving from actuation of a vehicle braking system includes incorporating a fiber-optic strain sensor of fiber Bragg grating type in a respective position in a portion of material of the body of the brake caliper susceptible to deformation, detecting, by the fiber-optic strain sensor local deformation and/or strain acting in the respective position, generating a respective first photonic signal representative of the detected deformation and/or strain, receiving the first photonic signal, by an optical reading/interrogation unit optically connected to the fiber-optic strain sensor, generating, by the optical reading/interrogation unit, a first electrical signal representative of the local detected deformation and/or strain, based on the received first photonic signal, and processing the first electrical signal to obtain a measurement of the braking force and/or braking torque. A sensorized brake caliper and a corresponding system to detect and measure a braking force and/or braking torque are also described.
