The monitoring of large structures typically require a variety of sensors based on different physical principles combined with set an appropriate set of diagnosis and prognosis methods. The monitoring is in tightly coupled aspect of nondestructive examination. This paper presents a new type of passive wireless sensors for monitoring of strain-stress. The sensor employs a special type of metamaterial named split ring resonator. In order to increase the sensitivity and the tuning of the desired interrogation frequency, the sensor use a self-assembled layer-by-layer single wall carbon nanotubes/graphene as well as an RFID tag. The key essential element for the wireless sensors, can be realized using a split ring resonator.
