This paper reports on the implementation of a structural health monitoring (SHM) system devoted to delamination detection on the wing box demonstrator. The developed SHM system is capable to control a network of up to 160 piezoelectric transducers that are surface mounted on the structure. The SHM system is able to perform both electromechanical impedance (EMI) measurement at each transducer to check their reliability and their bonding strength to perform an active guided wave (GW) screening. This latter operation exploits the damage detection methodologies that have been developed in the AS05/IS12 scenario to detect damages. Some information and results of a first experimental test carried out at the ALENIA facilities will be given.
