“…The research is described in a few publications by Finnish and American researchers [ 9 , 23 , 24 ]. The classic/galvanic connection of the semiconductor chip with the antenna is used in the presented construction (the same as in [ 25 , 26 ]). Such a connection is vulnerable to the damaging effects of environmental hazards that occur throughout the life cycle of products.…”

Recent advances in the development of innovative textronic products are often related to the implementation of radio-frequency identification (RFID) technology. Such devices contain components of wireless telecommunications systems, in which radiofrequency circuits should be designed taking into account not only the frequency band or destined application, but also the dielectric properties of the materials. As is known from the theory of RFID systems, the dielectric permittivity and loss angle of the substrates significantly affect the performance of RFID transponders. Therefore, the knowledge on the variability of these parameters is highly important in the context of developing new solutions in textronic devices with the RFID interface. According to the plan of studies, at the beginning, the comprehensive characterization and determination of the dielectric parameters of various types of textile substrates were carried out. On this basis, the influence of fabrics on the performance of textronic RFID (RFIDtex) tags was characterized with numerical calculations. As the RFIDtex transponders proposed by the authors in the patent PL231291 have an outstanding design in which the antenna and the chip are located on physically separated substrates and are galvanically isolated, the special means had to be implemented when creating a numerical model. On the other hand, the great advantage of the developed construction was confirmed. Since the impedance at the chip’s terminals is primarily determined by the coupling system, the selected fabrics have relatively low impact on the efficiency of the RFIDtex transponder. Such an effect is impossible to achieve with classical designs of passive or semi-passive transponders. The correctness of the simulations was verified on the exemplary demonstrators, in threshold and rotation measurements performed at the laboratory stand.

“…In the first case, a device outside the human body, the main technical specificity is where the device is still on a human body and we then find ourselves with the same issues as those of the wearable. It is then the antennas on textile support or adapted to textiles need to be developed [ 89 , 90 ], and in the case of RFID there is a need to integrate the sensor function [ 91 , 92 , 93 ].…”

RFID (radio frequency identification) technology appeared nearly 70 years ago. Deployed more widely only from the early 2000s, it is now booming and its development is still accelerating. As its name indicates, its original function was the identification (of objects, animals, people) and its applications were then essentially aimed at traceability, access control and logistics. If this type of use is still relevant today with more and more new application contexts and more and more efficient RFID tags, RFID has also evolved by integrating new capabilities. These new tags, known as augmented tags, include an information capture function. With the explosion of connected objects and the emergence of the Internet of Things (IoT), this old technology that is RFID still has a promising future and will probably be more and more present in our private and professional environments in all fields: logistics, industry, agriculture, building, health and even space.

“…At present, most of the applications based on RFID traceability system belong to single traceability, and many traceability information is only focused on planting nodes, and the management of agricultural product traceability information closure information has not been implemented [6]- [7] . Agricultural products involve multiple links in the circulation process, and it is difficult to unify the synchronization of traceability information based solely on RFID tags, resulting in low accuracy of traceability data and errors that make it difficult to ensure the accuracy of traceability data [8]- [10] . Traceability data is stored in a central database, and if the database is subjected to tools, the data can be easily leaked and tampered with [11]- [13] .…”

The system uses blockchain technology, centralized database, and RFID tags to build a secure agricultural product traceability system, which can retain the detailed information of agricultural product traceability and ensure that the summary information of agricultural products on the chain cannot be modified; The reader device uses the SM3 algorithm to summarize the original agricultural product traceability data and upload it to the central database, add the timestamp of the summary data to the chain storage, and write the summary data into the RFID tag User area. Realize the linkage of traceability data of agricultural products to ensure the accuracy of data. The overall architecture of the system mainly includes RFID readers, RFID tags, blockchain platforms, and centralized storage platforms. This system optimizes the SM3 algorithm to improve the execution efficiency, the execution time of 192 byte message is 210 µs, and the experimental results show that the algorithm efficiency is increased by about 30%, which can meet the requirements of agricultural product traceability data using SM3 to complete the summary.
