“…The review carried out herein, however, is different from the previous survey articles [13]- [28] in several ways. Comparing with the articles from [13] to [25], our paper provides a comparative survey on both the established RFID tag technologies which are silicon based and Surface Acoustic Wave (SAW) based.…”

“…Comparing with the articles from [13] to [25], our paper provides a comparative survey on both the established RFID tag technologies which are silicon based and Surface Acoustic Wave (SAW) based. While paper [28] discusses chipless RFID tags, it neither covered all chipless RFID technologies nor provided detailed insights on important aspects such as privacy and security. Papers [7] and [26] focused only on silicon based IC active and passive tags and a general description on silicon based IC tags, without a detailed comparison addressing all performance metrics that affect tag performance metrics such as read range, cost, security and privacy and longevity.…”

“…Furthermore, the conductive ink properties tends to degrade if the ink is exposed to extreme conditions. Despite being attractive in terms of cheaper cost, those other negative aspects have severely impacted the penetration of chipless RFID tags in the market [28]. Hence, the chipless RFID tags are ignored in this review.…”

“…Hence, the chipless RFID tags are ignored in this review. SAW RFID tags, on the other hand, are considered superior in those aspects and are therefore included in the review although bringing down the cost of SAW tags is still a challenge [28]. When possible, we also offer a quantitative comparison of these RFID tags across these performance metrics to provide a quick overview.…”

Many Automatic Identification (Auto-ID) technologies such as bar codes, magnetic stripes, Optical Character Recognition (OCR) and Electronic Article Surveillance (EAS) security tags are in existence. However, they are limited by a variety of constraints on them such as limited object rate of scan, need for Line-of-Sight (LOS) operation, very small interrogation range and poor accuracy in complex environments. Research has accordingly grown rapidly in recent years into the development of robust identification or tracking mechanisms. Radio Frequency Identification (RFID) technology using readers and RFID tags, whether passive, semi-passive or active in nature, has been deemed to be a promising candidate. Silicon based IC tags are quite popular. However, some alternative RFID technologies have also been on the rise. In particular, another special type of tag based on Surface Acoustic Wave (SAW) design also has a great potential for deployment in future identification fields due to its ruggedness against harsh conditions, metallic environments, interference, small and low cost and is being thoroughly reviewed, which is ignored in other survey papers. While other chipless RFID systems based on conductive ink, ink-tattoo and others do exist, negative aspects such as inability to survive in extreme weather, larger tag size and limited data storage capacity have severely impacted the penetration of such tags in the RFID market. Therefore, the scope of this survey article does not include chipless RFID tags. This article instead provides a comparative survey of silicon based IC and SAW based tags, which has attracted much attention from both academia and industry. The underlying characteristics, principles, advantages, and limitations of such tags are thoroughly discussed, and relevant research work followed by frequency of operation and other parameters are elaborated. This article undertakes a thorough investigation into the evolution of RFID technology and comparison into the current trend in silicon based IC and SAW based RFID tags and provides a comparison across many metrics, such as read range, tag size, tag power, availability of tag power, lifespan and more importantly, cost and security. It discusses active and passive tags under silicon based IC and SAW technology. Finally, the article reviews recent advances and provides potentials, open challenges and future research directions in such RFID tags.

“…Despite the fact that coupling modulation sensors operate at a single frequency, their robustness against noise is limited [17]. Nevertheless, the functionality of electromagnetic encoders as a low-cost alternative to optical encoders has been demonstrated [21], [23], [24]. An additional advantage of electromagnetic encoders over their optical counterparts is the possibility to operate in environments subjected to harsh and hostile conditions (i.e., with dirtiness, grease, pollution, etc.).…”

In this paper, a displacement sensor based on an open-ended step-impedance transmission line is reported. The sensor operates in reflection, and the output variable is the phase of the reflection coefficient. The static part of the sensor is the step-impedance transmission line, where the open-ended line section is the sensitive part (sensing line). The movable part is a dielectric slab, e.g., an uncladded microwave substrate. When such slab, located on top of the sensing line, is in relative motion to the line, in the direction of the line axis, the portion of the sensing line covered by the slab varies, and this results in a change in the phase of the reflection coefficient of the line. The step impedance discontinuity contributes to optimize the sensor sensitivity, the key parameter. A detailed analysis providing the design guidelines is carried out and used to design a prototype displacement sensor. The characterization of the fabricated device points out the potential of the approach to implement highly sensitive displacement sensors. The sensor is a one-port device and operates at a single frequency.
