“…A similar approach is taken in Reference [140] by Vena et al that uses loop resonators coated with Si nanowires for the sensing of humidity. Other implementations of interest include the multi-parameter sensor outlined by Amin et al [127], which makes use of two ELC resonators and a set of hairpin/C-section slot resonators, the latter of which are used for addressing, and one of the other resonators was coated with PVA for humidity sensing. The electric LC resonator, as shown in Figure 9, is a negative-ε structure which has fewer unwanted self-coupling effects than its SRR-based equivalent [141].…”

“…CRLH-based transmission lines have been used for contactless permittivity and velocity detection in the works of Puentes et al [51] and that of Penirschke et al [50]. The low-frequency, compact tag found in Reference [127] is a CRLH transmission line that can be used as a capacitive-type sensor. As described earlier, such a transmission line can be built out of regular inductors and capacitors, and in this case, utilises the large planar capacitors as a region for permittivity monitoring.…”

Chipless Radio Frequency Identification (RFID) has been used in a variety of remote sensing applications and is currently a hot research topic. To date, there have been a large number of chipless RFID tags developed in both academia and in industry that boast a large variation in design characteristics. This review paper sets out to discuss the various design aspects needed in a chipless RFID sensor. Such aspects include: (1) Addressing strategies to allow for unique identification of the tag, (2) Sensing mechanisms used to allow for impedance-based response signal modulation and (3) Sensing materials to introduce the desired impedance change when under the influence of the target stimulus. From the tabular comparison of the various sensing and addressing techniques, it is concluded that although many sensors provide adequate performance characteristics, more work is needed to ensure that this technology is capable/robust enough to operate in many of the applications it has been earmarked for.

In the modern world, Radio Frequency identification system plays a major role that automatically identifies and tracks tag attached to an object. RFID technology has been extensively used in many areas including agriculture, manufacturing, healthcare, transportation, etc. RFID system can be used in hospitals to increase the safety of patients by providing an RFID tag to the persons who visit them including doctors, nurses, and relatives. This method can be used along with a door lock but in the case of emergency, it becomes risky. Also, the same method can be used for secured access to pharmaceutical supplies which avoid illegal access to the medicines. Sensor network which is the core of IoT technology can be integrated with the RFID system to make it more efficient to be deployed in several application services. In this paper, a solution is proposed that can integrate the RFID system with the IoT technology by using IR sensors which help to get rid of illegal entry or access in hospitals.

“…In order to significantly reduce the cost per tag, chipless RFID tags, where no active electronics is present, have been developed. However, until this date, a completely passive, printable, low cost, mass deployable, environmentally friendly chipless RFID tag has not been reported . The chip removal has enabled the diffusion of new circuit fabrication techniques, which have paved the fabrication of circuit on unconventional substrates, such as polymers, textiles, and plenty of materials never adopted for electronics before …”

Biodegradable polymers represent an alternative to the conventional ones. The polyhydroxybutyrate (PHB) is one of the most used biodegradable polymers. However, PHB presents narrow processing window, which limits its applicability. The development of PHB composites offers a solution for that drawback. In this work, PHB and hollow glass microspheres (HGMs) composite films are developed. Subsequently, the films are characterized, and the biodegradability of the films is determined by the Sturm test. A suitable distribution and intermediate dispersion of the filler throughout the matrix are observed, while adhesion between the components is not achieved. The HGM does not significantly affect the thermal properties of the systems, however, decreases the degree of crystallinity. In addition, the composite films present small values of elongation and tensile strength than the pure PHB film. Finally, the HGM modified the mechanism of biodegradation; however, there was no change in the rate of biodegradation. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47195.
