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.

“…For instance, power for sensors was scavenged from bridge vibrations in [5], while in another scenario an air core coil was connected to a voltage doubler to collect power in [6]. RFID technology was employed in [7][8][9] to transfer power by inductive coupling between master and sensor magnetic coils. In addition, the effects of concrete's dielectric constant and loss tangent to the radiation pattern and gain of a microstrip patch antenna were studied in [10].…”

Wireless power propagation via Strongly CoupledMagnetic Resonance (SCMR) by helical resonators through a non-homogenous interface, such as, air-concrete, is analyzed here. The power transfer mechanism consists of two self-resonant coils and two single loops in contrast to the two resonant loops traditionally used in RFID systems. The efficiency of wireless power transmission from a source in air to a sensor embedded in concrete via strongly coupled magnetic resonance is simulated as well as measured. The concrete material is modeled for various humidity levels using the extended Debye's model. The efficiency of the SCMR is also analyzed for different depths inside the concrete.

“…Previous efforts at The University of Texas at Austin have led to the development of novel Electronic Structural Surveillance (ESS) tags to monitor various characteristics of steel reinforced concrete using wireless techniques [1][2][3][4][5][6][7][8]. Unlike many sensors either on the market or under development elsewhere, these sensors are designed to be extremely simple and low cost.…”

In situ measurement of conductivity and temperature during concrete curing using passive wireless sensors

et al. 2007

In this paper a new low cost, wireless unpowered sensor will be discussed that is designed to monitor the conductivity of concrete, which may provide information on the ingress of chloride ions during the life of the structure. A method of extracting temperature information from a previously developed corrosion sensor will also be presented. During a recent test, both a wireless corrosion sensor and a wireless conductivity sensor were placed in concrete and monitored throughout the duration of the curing process. Analysis of the data shows it is possible to determine temperature information based on the corrosion sensor response, allowing wireless in-situ temperature monitoring of the concrete during the cure. Monitoring curing temperature using the same sensor which would later be used for long-term corrosion detection would help reduce the cost of such a monitoring system.
