... identification (RFID) technology is attractive for biosensing applications because the sensors can be wirelessly interrogated when operating in a concealed, packaged or in a bio-hazardous environ- ment where direct measurement is not considered to be practical. The scenario is specifically relevant for monitoring a product supply-chain (shown in Fig. 1) where the use of passive RFID tagging technology is becoming more wide-spread [1], [2]. Integrating biosensing capabilities with passive RFID tags ensures that the sensors are low-cost and because these sensor-tags operate without batteries, their shelf-life is comparable to the products being monitored.

To facilitate complex interactions between regional players and the agricultural environment, modern agriculture supply chains have arisen. Supply chain processes that include several parties, such as production, processing, and delivery, interacting with one another. Lack of transparency in the agricultural supply chain is a major contributor to the incidence of fraud in this industry. A lack of openness on the part of organisations leads to worries about potential financial losses, diminishing customer trust, and dwindling brand value. Several fundamental changes to the existing supply chain architecture are required to foster the development of an effective and reliable trade environment. It is widely recognised that blockchain technology has the potential to increase visibility across agricultural and food supply chains. Businesses are using blockchain and IoT to implement more egalitarian, sustainable, and consumer-friendly methods of food production. Based on what we learned, blockchain technology may be useful in the push for a more transparent and responsible food supply chain. The primary goal of this study is to create a decentralised application framework called AgriBlock that can be used for managing the supply chains of agricultural products using blockchain technology. The developed work AgriBlock will aid in making the supply chain process more open and clear to every participant involved.

Direct measurements of analytes, which are normally thought to be unfeasible in real-time, are made using RFID antennas created for microfluid biosensing that are resonant at 915 MHz with the polyethylene substrate [18].

A metamaterial resonating antenna design having a hexagonal patch is proposed for biosensing applications to work in triband resonating frequencies at 5.2GHz, 9.6GHz, and 18.5GHz. The hexagonal patch is built on a dielectric constant of 4.4 FR4 epoxy substrate with a loss tangent of 0.030. Two different antennas are designed and tested with conducting metallic patches bounded by split ring resonator (SRR) slots and closed ring resonator slots which are also hexagon-shaped. Each antenna is capable of resonating at different frequency bands with good wide band characteristics due to the presence of partial ground plane. The hex-SRR resonates at 1.9GHz and 3.1GHz and hexagonal-CRR resonates at 5.2GHz, 9.6GHz, and 18.5GHz frequency bands resulting in multiband resonance characteristics. The proposed antenna is also validated with the study of metamaterial property of hexagonal SRR at the resonant frequency of 5.2GHz hence resulting in a compact (20 × 20 × 1.6) \(mm^3\) and more dominant design. Furthermore, the specific absorption rate (SAR) for the three-layer phantom model is confirmed, resulting in superior performance that is more appropriate for biosensing and on-body wearable devices. The testing is performed using an E5063A ENA vector network analyzer provided by Keysight Technologies. The measured and simulated results are very close, resulting in a better validation of the proposed work.

The development of several novel food packaging techniques is seen in the market that help the consumer monitor their quality, safety, integrity, cleanliness, freshness, and purity until they are being consumed. In addition to this, there is a need to minimize food corruption, counter-theft, spoilage, contamination, and efficient food safety communication. Several current technologies for packaging, such as intelligent packaging and active packaging, have been established to meet this requirement. In this review paper, we discussed various types of intelligent packaging systems like indicators, sensors and data carriers. Indicators indicate the current status of food products from the inside by giving visual signals like color change. Sensors, which are digital in nature, detect the changes that occur in the product with the help of transducers and signal processors. Finally, a brief discussion about data carriers and their classification, such as Bar codes, QR codes, Radio Frequency Identification Devices, and Near Field Communication Systems, is given. These systems help to track the product in supply chain and inventory management.

India and other developing countries arefacing issues for coordination of their Agriculture Food Supply Chain Management (AFSCM) as not having technical and resources support; especially in natural disaster condition like recent COVID-19 outbreak. The purpose of this research is to develop anInternet of Things (IoT) based efficient and supportive coordinating system for enhancing the coordinating mechanism in AFSC under natural outbreaks. With the help of a literature review and experts’ inputs, seven enablers have been identified by grouping thirty sub enablers. Further, ISM methodology has been employed for developing a framework for enablers’ relationships to improve the coordination in the AFSC for taking strategic and operational decisions. After that, DEMATELtechnique is utilised to develop the causal and effectrelationships between all the identified enablers of a coordination system in IoT based AFSC. It has been noticed that‘Top Management Support (TMS)’ is the main driver by MICMAC analysis and categorised in a cause group based on (R-C) value. Further, the coordination index of the entire model is calculated based on the Cleveland theory. This paper also discussed a case study of the sugar mill industry. This paper also discussed stakeholder theory in developing IoT based coordination system of AFSC. Further, theoretical contribution may also guide the managers of the organisation in developing their strategies by using Strengths-Weaknesses-Opportunities-Threats (SWOT) analysis based on Cleveland index.

This paper addresses two key challenges toward an integrated forward error-correcting biosensor based on our previously reported self-assembled quick-response (QR) code. The first challenge involves the choice of the paper substrate for printing and self-assembling the QR code. We have compared four different substrates that includes regular printing paper, Whatman filter paper, nitrocellulose membrane and lab synthesized bacterial cellulose. We report that out of the four substrates bacterial cellulose outperforms the others in terms of probe (gold nanorods) and ink retention capability. The second challenge involves remote activation of the analyte sampling and the QR code self-assembly process. In this paper, we use light as a trigger signal and a graphite layer as a light-absorbing material. The resulting change in temperature due to infrared absorption leads to a temperature gradient that then exerts a diffusive force driving the analyte toward the regions of self-assembly. The working principle has been verified in this paper using assembled biosensor prototypes where we demonstrate higher sample flow rate due to light induced thermal gradients.

Development of antenna sensors is attractive for environment monitoring due to widely distributed readout devices, such as smartphones, tablets, etc. However, the remaining challenge is how to realize quantitative detection of a designated concentration of analyte.

The Bluetooth-enabled antenna sensor was made by mechanical abrasion of a 2B pencil to form a stripe of graphitic coating on a printed silver dipole antenna. The RSSI evaluation model was used to acquire different concentration levels of humidity. The experimental results are consistent with the simulation outcomes.
