“…During the development of RF sensors based on 2D materials, sensing schemes including RLC circuits based on mutual inductance [41,42], RFID tag-antenna coupling [43,44] and near-field communication (NFC) [45,46], were routinely adopted both in the laboratory and in practical applications (figure 2). Attempts were made to develop graphene-like nanosheets gas sensors based on the surface acoustic wave wireless technology in 2008 [47].…”

As one of the most promising platforms for wireless communication, radiofrequency (RF) electronics have been widely advocated for the development of sensing systems. In particular, monolayer and few-layer two-dimensional (2D) materials exhibiting extraordinary electrical properties not only can be integrated to improve the performances of RF circuits, but also to display exceptional sensing capabilities. This review provides an in-depth perspective of current trends and challenges in the application of 2D materials for RF biochemical sensing, including: i) theoretical bases to achieve different sensing schemes; ii) unique properties of 2D materials for reasoning their applications in RF sensing; iii) developments in 2D RF sensors to facilitate the practice of biochemical sensors with ever-demanding sensitivities, as well as their potential uses in meeting the requirements and challenges of biochemical sensors in the Internet-of-Things (IoT) era.

“…We can see that the modified method with four phases performs much better than the original method especially in the cases of large variance σ. For example, with σ= [4,1], the estimated distance value of 𝑑 3 (when 𝑑 3 was set to be 0.5 m) using one-phase method is 0.05 m and that using four-phase method is 0.36 m.…”

“…Passive tags are smaller and less expensive than active tags. They provide nearly unlimited operational lifetime and can be easily embedded in the environment, and hence can greatly enable the infrastructure of the Internet of Things (IoT) [2][3][4] where a large-scale deployment with connectivity is required.…”

Radio Frequency Identification (RFID) is a rapidly growing technology that uses radio frequency signals to transfer data among devices. Recent works have proposed a novel reader-free RFID system where tags can communicate with each other directly with the existence of a continuous wave (CW) from some external RF carrier source or an ambient RF signal. In this paper, we propose the log-power difference as observations for the localization and tracking problems in passive Tag-to-Tag communication systems. The likelihood function of the log-power difference is derived in a seminumerical semi-analytical way. The proposed observation model is validated through estimating the distance between the two tags using maximum likelihood method. The results demonstrate the advantages of the modified method with multiphase backscattering where it shows a significantly improved estimation accuracy with more phases. The analysis is further extended to an infinite number of phases, where the maximum received power is obtained.

“…Rapid surge in progression of RFID technology has brought great attention towards chipless tags in the recent years. RFID is a wireless technology that is essentially used for automated identification of objects by using radio frequency (RF) waves [1]. A conventional RFID system consists of two integral parts, 1) RFID tag and 2) RFID reader [2].…”

In this paper, a unique structural design methodology for chipless radio-frequency identification (RFID) tags in frequency domain is presented. The tag geometry is developed by loading an open-loop resonator with micro-metallic-cells (MMC). The realization give rise to a checkerboard resonator type with electromagnetic signatures in its radar cross section that are extremely efficient to manipulate. The resonators layout is distributed on either side of a Rogers substrate to double its coding density. The proposed chipless RFID tag has a memory of 8-bits in total. The operating band of the tag is 6.5-10.5 GHz. The tag has a high bit coding density of 10.94 bits/cm 2 and spectral efficiency of 2 bits/GHz. The tag has a very compact size of 17.4 × 4.2 mm 2 . The simple structuring methodology and efficient resonators layout will give RFID system designers the flexibility to apply the proposed tag in a wide range of modern applications.INDEX TERMS Chipless radio frequency identification (CRFID), frequency-domain (FD), miniaturization, open-loop, radar cross section (RCS), resonators, tag.
