The use of textronic RFID transponders (RFIDtex tags) offers completely new possibilities in designing household appliances. Their implementations in technologies of washing or ironing textiles are very promising. Specific information on maintaining clothes can be stored in the memory of RFIDtex tags that are permanently bound to the products. This information can be read by washing or ironing devices and then can be used to automatically select the best program or mode of machine operation. Since RFID technology is becoming more and more common, the solution seems simple and ordinary. Nevertheless, there are some barriers that prevent the popularization of such applications. Reliability and efficiency of identification are major concerns, especially near surrounding objects, such as other tags, material composition of textiles, and above all, metal drums of washing machines. The main purpose of the presented work is to propose the communication model in the anti-collision dynamic RFID system, dedicated to use in future intelligent industrial and home washing machines. To develop the elaborated idea, the washing machine demonstrator equipped with read/write RFID devices was designed. Moreover, the RFIDtex transponders according to the authors' conception (restricted under Polish patent, No. PAT.231291) are used in experimental stages. As part of the work, appropriate reading and scanning algorithms were developed to manage multiple data readings from tags inside the drum. Also, measurements were carried out to confirm the identification efficiency in such an Internet of Textile Things (IoTT) system basing on the RFIDtex tags that are placed inside the demonstration washing machine.

The aim of this paper is to demonstrate progress in textronic UHF RFID transponder (RFIDtex tag) technology. The fundamental idea behind the RFIDtex tag design involves galvanic separation between circuits of the sewn antenna and the chip, which are electromagnetically coupled through a system of inductive loops. To advance the development of this concept, it is crucial to detect factors affecting the performance of the transponders. To achieve this goal, a mathematical model of the textronic UHF RFID transponder was developed. It involves relationships that describe the impedance of each element, the mutual inductance of the loops, and the chip voltage, and it enables the exploration of the influence of these variables on general parameters such as impedance matching and read range. Various analytical and numerical approaches were considered to obtain the value of the mutual inductance of the loops. The dimensions and geometry of the antenna, as well as the matching circuit in the microelectronic module, were taken into account. Based on the mathematical model, it was determined that mutual inductance strongly affects the chip voltage for frequencies higher than 800 MHz. The calculations from the mathematical model were compared with numerical simulations. Experimental studies were also conducted to investigate how the transponder performance is affected by either the distance between the centers of the loops or the conductivity of the threads used to embroider the antenna. The measurement results allowed us to conclude that even small imperfections in the manufacturing of the transponder, which slightly increase the vertical or horizontal distance between the centers of the loops, cause a dramatic decrease in the mutual inductance and coupling coefficient, significantly impacting the transponder’s performance.

“…For the first methodology, the analysis has been focused on the evaluation of the sensitivity of the device when different volumes of water droplets have been placed on its surface. The working frequency for this study is around 4.6 GHz, (suitable for Internet of things [35] sub-6GHz band of 5G [36], [37] and RFID [38], [39]). The idea behind this choice regards the advantages of using the RFID technology for future applications of the proposed sensor.…”

In this paper, a minimally invasive dielectric sensor with a compact footprint of 24x18 mm 2 is presented. It is based on two complementary split ring resonators (CSRRs) fed by a microstrip with coplanar waveguide configuration and placed on a 200 μm thick Kapton substrate. The device has been fabricated by means of a multi-material 3D printer NanoDimension's Dragonfly IV and is characterized by exploiting two different sensing methodologies. As a first step, the device has been characterized in the air by measuring the volume of deionized water droplets placed on one of the CSRRs in the range between 3.6 μl and 9.6 μl. This study has been performed through the analysis of the resonant frequency shift caused by the variation of the dielectric constant. The results show a Q-factor of 702 and a sensitivity of 0.3% μl -1 . Then, an additional step has been carried out for the measurement of the temperature of the water in which the sensor is totally dipped. We analyzed the frequency shift due to the water temperature variation in the range between 20°C and 40°C which corresponds to a variation in relative permittivity. In this case, the sensor shows remarkable results in terms of Q-factor, equal to 501, and a sensitivity to dielectric variations in out-of-body and in-body temperature ranges equal to 0.5% and 1.5%, respectively.
