“…New sensing elements such as MEMS [ 6 ] or nanosensors [ 2 ] have also appeared, among those a large variety of strain, force and temperature sensors based on piezoresistive nanocomposite materials 2 [ 7 ]. A very strong focus lies on the demonstration of wireless communication through concrete with passive or battery operated devices (passive RFID tags, 802.15.4 nodes) to create the so-called "smart pebble" [ 8 ], or "smart aggregate" devices: wireless sensor nodes which incorporate several sensing elements, computing and communication capabilities, power supply and storage, and roughly sized like a concrete aggregate.…”

The development and test of a smart RFID-based corrosion sensor is presented. The sensor has a small size (5 cm x 3 cm x 1.8 cm) allowing it to be embedded in concrete or other construction materials. The corrosion sensor is built around a low-power microcontroller which enables multiple and complex measurements to take place. The sensor is totally passive and it does not require batteries. Its power supply is derived from an electromagnetic field transmitted by an external RFID reader. This field is also used for data communication. The sensor contains a potentiostat that is used to perform linear polarization measurements on a corrosion cell. The sensor can also measure temperature and its own supply voltage. Unlike existing embeddable corrosion sensors, the developed sensor can acquire full polarization curves with a resolution of 10 bits. The sensor can communicate with ISO-15693 compliant RFID readers.

“…To overcome these problems, there is increasing interest in the integration of RFID (Radio Frequency Identification) and sensor networks for structural health monitoring. [1][2][3][4][5][6][7][8][9][10] RFID is a technology that transmits information between a reader and tags attached to an object using electromagnetic induction for the purpose of identification. It is widely used as IC tag or IC card.…”

“…There are several researches about using RFID sensor tag for SHM. For example, Watters et al 2,3) have developed a wireless sensor for monitoring the level of chloride ingress into concrete bridge. Morita et al 4) and Chin et al 5) have proposed a wireless sensor which can detect the presence of cracks and deformation in structures using electrically conductive paint or thin copper strip.…”

A new sensor, which can estimate fatigue damage parameters such as number of cycles and stress amplitude, was proposed and fabricated based on smart stress memory patch. This sensor composed of an ion-sputtered metal film deposited on the smart stress memory patch (a thin copper specimen). The crack extension of the sensor during fatigue test could be estimated by measuring the electrical resistance change of the ion-sputtered metal film. The relationship between normalized electrical resistance and the crack extension obtained from the experiment showed a good agreement with that predicted by FEM analysis. This new sensor was combined with two wireless systems using commercially available wireless module and RFID tag. The capability of these systems was evaluated and the results showed that both systems were successfully applied to measure the crack length of the smart stress memory patch. It demonstrated that the proposed systems have potential as a wireless sensor for structural health monitoring, which enable long-term fatigue evaluation with features of easy configuration, wireless and powerless.
