This paper addresses the interference issue in a passive multi-cell radio frequency identification (RFID) system. Instead of considering the negative effect of interfering RF signals from adjacent readers, we investigate its constructive effect in providing extra RF power to tags in the cell of the desired reader system. Through detailed simulation and experimental analysis, it is found that the unsynchronised signal from neighbouring readers can be utilized to activate marginal tags through enhancing power delivery. This results in improved tag received signal strength indicator (RSSI). In addition, it is found that the overlap zone between two RFID cells is not as vulnerable to interference as one might think. In fact, the adjacent reader may facilitate the desired reader to read more tags in the overlapping zone, although a longer inventory period may be required. We believe these findings might provide a new insight into the interference effect on multi-cell RFID system and be applied to future medium access control (MAC) protocols.

Inkjet printing is one of the emerging methods for fabrication of electronic devices. The important issue in this area is developing nanomaterial-based inks for different applications such as gas sensors for environmental monitoring. In particular, graphene-based materials have recently gained interest due to their extraordinary properties. However, graphene has hydrophobic nature resulting in poor solubility in the most of the solvents. In order to solve this problem, graphene oxide is mostly used instead of graphene. To retrieve the conductivity, the printed samples are reduced to remove the oxygen containing groups. The major contribution of this paper is focused on the production of conductive graphene-based patterns on the flexible kapton substrate utilizing thermal reduction process. Both printed samples and inks were characterized and analyzed to enhance the quality of printing. The effect of different parameters such as surface modification, annealing condition, thermal reduction atmosphere, setting of inkjet printer, and concentration of ink were investigated. The characterization part includes analysis of the morphology, sheet resistance, conductivity, and viscosity of ink. This work is an important step for future research on the development of wireless graphene-based gas sensors.

This paper presents a novel method for accurate indoor localization, utilizing the embroidered passive Radio Frequency Identification (RFID) tags. The feasibility of RFID tags for positioning and localization applications is studied here and a comparison to WLAN system is done. An indoor localization system based on the received signal strength (RSS) measurement requires the determination of the suitable path-loss model of the measurement environment for creating a low complexity positioning estimators. In this paper the path-loss model and its parameters, using an embroidered passive RFID tag is introduced. The backscattered power measurement of the embroidered passive tag on human body, for certain measurement points, in indoor environment, is performed. The path-loss model is calculated utilizing the collected RSS data and deconvolution approaches. We show that the RFID RSS values are slightly more stable than the WLAN RSS values (i.e., lower shadowing variance) and that the two-parameter path-loss models are suitable to characterize the RFID RSS fluctuations.

This work concerns the prototyping of a low cost PCB based multiple loops antenna for LF 125 kHz RFID application. The multiple loops structure is considered for the context of small tags traceability, for example token tags such as circular HitagS (1-2 cm of diameter). The targeted volume is 20×20×10 cm3 for the moment. The position of the tag can be parallel or orthogonal to the reader antenna plane, with a variation of the angle position, and is moving inside the volume of detection (small objects in a storage basket in practice). The dedicated conception of a reader antenna is necessary because the application targets a volume of detection rather than maximum range detection. Additionally, the position of the tag is not known. The design considerations are based on a combination of Identical Coaxial Loops (ICL) and in/out-of phase loops structures whose advantages are discussed in terms of mutual inductance in the simulation part. An optimum diameter of 7,5 cm is noticed for square loops case. The realization of this structure shows qualitatively good results for our objectives and emphasizes a tradeoff between the two effects of coupling due to the two structures combined. As the tag is moving inside the volume, with an orientation (tag position test) unknown, our observations drive to the conclusion that the detection will be effective. Some perspectives are also clearly identified to improve the structure in the future.

In this work a Genetic Algorithm is used to obtain optimal planar UHF RFID tag antenna topologies. The presented antenna design method is automated and solely requires very little human intervention. Different requirements like antenna dimension, conductive and dielectric materials, frequency range, etc. can be adjusted. This enables the automated design of tailored tag antennas for different requirements. Due to the complex behavior of UHF antennas numerical electromagnetic field simulation is essential. Simulation is carried out with the aid of ANSYS HFSS and ANSYS DESIGNER. In order to obtain meaningful results, high accuracy of the simulation is of vital importance. Therefore this work places emphasis on the comparison of simulation and measurement of prototypes. As a result of the evolutionary design, examples for narrowband and broadband antennas are presented. Two approaches were applied, one very fundamental, discretizing the available design space into pixel units. In addition a lattice based approach, promoting meander-like layouts, is implemented. Four antenna layouts are discussed in this work. All obtained tag antennas meet the required specifications and prove the abilities of the design approach.

Real-time and continuous wireless measurement of human body temperature could enable a better control of many pathologies such as the wounds infection after surgery and the evolution of epidemics involving fever rush, as well as the monitor of athletic activities. This paper describes an RFID passive UHF epidermal sensor suitable to be directly attached onto the human skin by means of a bio-compatible transpiring Poli(ε-caprolacton) (PCL) membrane. The antenna elements provide a broad matching band and even a post-fabrication tuning mechanism to better manage the specific placement over the body. The temperature is directly measured by the EM4325 microchip, also providing RFID communication capabilities. The epidermal sensor, that can be read up to 35 cm in case of 0.5 W EIRP emitted by the reader, has been moreover thermally calibrated versus a thermocouple and then applied to the measurement of human body temperature in both static and dynamic conditions with an accuracy of about 0.25°C with respect to reference measurements.

In this paper we introduce for the first time the concept of exploiting the rectifier part of passive RFID systems not only for sensor powering but also for remotely performing the sensor reading. This solution is proposed for harsh industrial environments where remote machineries parts need be simultaneously powered and monitored wirelessly. We demonstrate the co-existence of high wireless power transfer and NFC communication for temperature sensor read-out, with no need for extra electronics at the RFID tag side to control the sensor readout. In particular, we show that the behavior of the RF-to-DC rectifier of a passive RFID, loaded by the sensor, can be exploited for powering the sensor operations as well as for reading its activities.

A witness to show the coexistence of multiple RFID tags is called grouping-proof and it is useful to handle a lot of commercial products in Internet of Things (IoT). Many of the existing grouping-proof protocols have a common problem that the RFID reader incrementally communicates with the RFID tags in the group and the round complexity is quite high. In this paper, we show that there exists a provably secure RFID grouping-proof protocol which the grouping-proof is generated in the constant round. Especially, we propose two-round RFID grouping-proof protocols secure against the impersonation attack and man-in-the-middle attack, respectively.

We present a fully printable, planar, orientation independent, single layer, chipless RFID tag. The tag consists of a circular patch with multiple discretized circular slot resonators nested in it. This design reduces the total size of the tag since the discrete circular slot resonators resonate at a lower frequency than perfect circular resonators for the same diameter. Reader's complexity is reduced as the tag is polarization independent, improving the tags readability from different angles with respect to the reader antenna. Its single layer characteristics make this tag a potential candidate for conductive ink printing. The frequency band is within 6 to 14 GHz.

All mechanical structures are subject to deformation, due to fatigue, stress and/or environmental conditions. It is therefore of uttermost importance to monitor the mechanical “health” of critical structures, in order to prevent catastrophic failures, but also to minimize maintenance costs, i.e. avoid unnecessary inspections. The present work hence shows a miniaturized RFID sensor, optimized for good operation on concrete and other “RFID-harsh” environments and able to detect deformations occurring on the object on which it is placed.
