[IEEE 2018 IEEE International Conference on RFID Technology & Application (RFID-TA) - Macau, Macao (2018.9.26-2018.9.28)] 2018 IEEE International Conference on RFID Technology & Application (RFID-TA) - Fabrication and Practical Evaluation of Glove-integrated Passive UHF RFID Tags
摘要： Passive RFID-based technology is a convincing approach to achieve versatile energy- and cost-efficient wireless platforms for future wearable applications. In this paper, we present passive UHF RFID tags integrated into normal work gloves for wearable RFID applications. We introduce embroidery as a new efficient antenna fabrication method for glove-integrated tags as well as establish reference glove-tag antennas from electro-textiles and copper tape. The performance of the three types of glove-tags is evaluated on a male test subject in an anechoic room and in an office environment. Based on the wireless measurement results, the read ranges of the embroidered glove-tags were around 1 meter in an anechoic chamber and in an office, when measured near the human body. These results meet the requirements of many practical applications of glove-tags, although the read ranges are shorter than those of the electro-textile and copper tape tags that showed read ranges of 2-2.5 meters. Finally, the developed glove-tags were successfully tested in actual use situations for identification and access control. These results are very promising, especially considering the cost-effectiveness of embroidered tag antennas and the easiness of their integration into different types of gloves.

摘要： We present a glove-integrated slotted patch antenna for a wearable Ultra High Frequency Radio Identification Technology (UHF RFID) reader operating at 866 MHz. We tested the prototype antenna made of copper foil adhered on low-permittivity Ethylene Propylene Diene Monomer (EPDM) foam material having the thickness of 4 mm. To characterize the antenna, we tested it wirelessly in communication with a common dipole type RFID tag to estimate its realized gain, radiation pattern and maximum tag read range it provides. We also analyzed the effects of variable separation between the antenna and the body to confirm stable operation required by the application. The results showed that the antenna feasible for the work glove applications providing the read range up to 360 cm with the reader’s output power of 28.4 dBm.

[IEEE 2018 IEEE International Conference on RFID Technology & Application (RFID-TA) - Macau, Macao (2018.9.26-2018.9.28)] 2018 IEEE International Conference on RFID Technology & Application (RFID-TA) - A widely linear MMSE RFID receiver with multi-antenna for physical layer collision recovery
摘要： In this paper, a novel widely linear minimum-mean-square-error (MMSE) anti-collision receiver for passive ultra high frequency (UHF) multi-antenna radio-frequency identification (RFID) systems is proposed. By establishing that real-world tag signals are essentially noncircular in the complex filed, the proposed widely linear estimator is proven to have better performance in recovering data from collision when compared with its linear counterpart. Simulations on tags in conflicting response is conducted, justifying the performance advantages of the proposed receiver over the conventional linear one.

摘要： We establish a passive UHF RFID tag as a sensor with a referenced readout to compression. We introduce the sensor tag design, which is based on a two-part split ring resonator antenna, and present the compression sensor platform with a reference tag. We analyze the achieved wireless measurement results and evaluate the performance of the compression sensing platform. Based on these initial measurements, passive RFID-based sensors could provide a maintenance-free wirelessly readable option for compression sensing, for example for structural health monitoring.

Fast Splitting Based Tag Identification Algorithm For Anti-collision in UHF RFID System
摘要： Efficient and effective objects identification using Radio Frequency Identification (RFID) is always a challenge in large scale industrial and commercial applications. Among existing solutions, the tree based splitting scheme has attracted increasing attention because of its high extendibility and feasibility. However, conventional tree splitting algorithms can only solve tag collision with counter value equals to zero and usually result in performance degradation when the number of tags is large. To overcome such drawbacks, we propose a novel tree-based method called Fast Splitting Algorithm based on Consecutive Slot Status detection (FSA-CSS), which includes a fast splitting (FS) mechanism and a shrink mechanism. Specifically, the FS mechanism is used to reduce collisions by increasing commands when the number of consecutive collision is above a threshold. Whereas the shrink mechanism is used to reduce extra idle slots introduced by FS. Simulation results supplemented by prototyping tests show that the proposed FSA-CSS achieves a system throughput of 0.41, outperforming the existing UHF RFID solutions.

摘要： The performance of RFID tags deteriorates when mounted on metallic objects. This is due to the induced eddy current effect on the metal which produces a magnetic field that opposes the reader/ tag field. Suitable electromagnetic screening is needed to mitigate this issue e.g. ferromagnetic films shielding the tag from the metal. This paper explores some design guidelines for ferrite films properties for additive manufacturing methods. Simulated and measured results for different ferromagnetic films and their influence on the performance of the NFC tags are investigated.

摘要： This paper presents a novel angle-based chipless RFID tag with high capacity. It encodes the information with the angle between two arms of the X-shaped scatterer and is identified through the orthogonal polarization. The advantage of this type of tag is that every unit can encode multi-bit information. Also, for different codes of one unit, the proposed tag occupies the same spectrum. This is helpful to improve the spectrum efficiency. Based on this, the tag is used to design the resistance transducer.

Spatial-Based Chipless RFID System
摘要： Conventional techniques in chipless RFID systems are incapable of fully overcoming the key challenges of modern identification applications, including high data capacity, low tag cost and reliable operation. The idea of electromagnetic (EM) imaging in chipless RFID systems is a promising technique that shows many advantages over other conventional approaches. This paper reviews conventional chipless RFID technology and provides a comprehensive analysis of advanced millimeter wave spatial-based (also known as image-based) chipless RFID systems with an optimized MIMO-SAR technique for high-resolution image acquisition and a quick reading process.

摘要： When food is stored under inappropriate or inadequate temperature, foodstuff would turn rotten as a result of the rapid breed of food spoilage bacteria under warm and wet circumstances where bacteria can be easily generated, the consequences can be worse if human beings eat those degenerative comestible, we might get bromatoxism. This paper focuses on the designing and simulation of a wearable radio frequency identification (RFID) patch for food spoilage monitoring with smart packaging that can be recognized and read temperature information by device supporting near field communication (NFC) technology through an attached circular antenna. More precisely, this patch can be read under a designed high frequency of 13.56MHz, and data is transmitted from the chip MLX90129 with its internal sensor that sends the temperature to the reader module.
