Abstract
A seal for a movable part of a motor-vehicle includes at least one body formed of polymeric elastomeric material supplemented with carbon-based nanofillers. The body includes an outer surface having one or more piezo-resistive areas where the polymeric material supplemented with carbon-based nanofillers is piezo-resistive due to laser irradiation to define one or more electric deformation sensors activatable in response to a contact with a foreign body during the movement of the movable part of the motor-vehicle. The body also includes one or more conductive lines made locally electrically-conductive due to laser irradiation to define the one or more electrical connection lines connecting the electric deformation sensors to electrodes associated with the seal.
