Special Issue Information

Dear Colleagues,

We are pleased to invite you to participate in the Special Issue of the MDPI Sensors journal with the title “RFID Sensor Technology in IoT Era”.

Radiofrequency identification (RFID) is a modern technology whose utilization has gradually expanded into a wide range of identification, tracking, and sensing applications, including the operation of transponders attached to lossy dielectric and metallic objects, human bodies, as well as the integration of RFID transponders with sensors.

Research of RFID with sensing of both electrical and non-electrical quantities is a large challenge for scientists worldwide. Sensing capabilities offered by RFID transponders in the UHF or microwave frequency band are emerging research trends with great applicability to the topical paradigm of Internet of Things, health-care and assisted living equipment, and safety tasks in chemical or other industries. Different transponder concepts are being developed: passive, semi-passive, and active; chip and chipless. Researchers in this field face many challenges that need to be met, such as the high sensitivity of transponder sensors, high range reading, manufacturing transponders by ink-jet or screen-printing technology, reliable identification requiring robust sensing and calibration methods, operation of transponders in complex environments, etc.

We would like to present the current advance in this topical technology through this Special Issue. Original research articles and reviews are welcome. Research areas related to RFID sensor technology may include, but are not limited to, the following:

  • Sensing transponders of electrical and non-electrical quantities;
  • Platform tolerant and wearable sensing transponders;
  • Passive, semi-passive, and active sensing transponders;
  • Chip and chipless sensing transponders;
  • High sensitivity and read range sensing transponders;
  • Ink-jet and screen-printing technology;
  • Robust sensing and calibration methods for complex environment;
  • RFID reader antennas and systems;
  • Internet of Things;
  • Review of state of the art;
  • Other topics.

We look forward to receiving your contributions.

Missing tag incidents are common in RFID-enabled supply-chain and warehousing scenarios due to cargo theft and employee error operations, which may lead to serious economic losses or potential safety hazards. On the premise of ensuring the accuracy of missing tag detection, this paper aims to improve the time efficiency in an integrated RFID system. Unlike prior work focusing on detecting missing items from a large number of homogeneous tags that are monitored by a single reader, one integrated RFID system possesses multiple readers to communicate with the heterogeneous tags, which have different categorical attributes. In addition, the prior work required repeating the execution several times to capture the missing tags in assorted categories, which is of low time efficiency. Thus, a protocol called Multi-reader Missing Tag Detection (MMTD) is proposed to capture the missing tag quickly and reliably, which can detect missing tags from different categories in a parallel manner and is much more time-efficient than previous work. MMTD has two major advantages compared to prior work: (i) It leverages the knowledge of the spatial distribution of tags to divide up a difficult detection task into several lightweight tasks, which are shared by multiple readers. (ii) It personalizes the time frame of the reader based on the tag population to optimize the utilization of the communication channel. The final simulation results reveal that MMTD is the best in time-efficiency among the comparison protocols, and MMTD outperforms the other missing tag detection protocols by at least 1.5× in the Integrated RFID scenarios.

The omnipresence of connected objects leads to the quasi-permanent presence of electromagnetic waves from different sources in our environment. This article presents a new electromagnetic energy harvesting device, rectenna type, which offers the advantage of being versatile. Indeed, the proposed prototype is compatible with three frequency bands of radio standards widely deployed today (UHF RFID, GSM-1800, and UMTS-2100), and its performances remain good for low to very low ambient power levels as well as for different loads depending on the targeted application. The proposed solution is based on a tri-band antenna with very good efficiency and a bandwidth of at least 80 MHz for each of the operating frequencies. Moreover, the associated rectifier circuit is also tri-band and offers good performance in terms of RF-to-DC conversion efficiency for input levels varying in a rather wide range of power levels. The study is based on a design phase by simulation until the realization of prototypes and their experimental characterization. The designed rectenna is compared with solutions found in the literature. Full article
