“…A comparison between the proposed RFID tag and several tag designs for blood and liquid monitoring is provided in Table 2. As it can be seen in Table 2, only one tag is applied to the monitoring of blood tubes [19], while the others are used for blood bags and different liquids. The tag for the monitoring of blood tubes is of capacitive dipole type, like the proposed tag antenna.…”

“…All of them are used in the monitoring of blood bags, except one which is applied to blood tubes. The antennas are mostly of inductive dipole type, although there is an example of a capacitive dipole type in [19] and a traveling wave antenna type in [20]. Two of the antennas are flexible [21,22], while the other three are not.…”

Low-cost and flexible radio frequency identification (RFID) tag for automatic identification, tracking, and monitoring of blood products is in great demand by the healthcare industry. A robust performance to meet security and traceability requirements in the different blood sample collection and analysis centers is also required. In this paper, a novel low-cost and flexible passive RFID tag is presented for blood sample collection tubes. The tag antenna is based on two compact symmetrical capacitive structures and works at the ultra-high frequency (UHF) European band (865 MHz–868 MHz). The tag antenna is designed considering the whole dielectric parameters such as the blood, substrate and tube. In this way, it operates efficiently in the presence of blood, which has high dielectric permittivity and loss. Measurement results of the proposed tag have confirmed simulation results. The measured performance of the tag shows good matching in the desired frequency band, leading to reading ranges up to 2.2 m, which is 4.4 times higher than typical commercial tags. The potential of this tag as a sensor to monitor the amount of blood contained in clinic tubes is also demonstrated. It is expected that the proposed tag can be useful and effective in future RFID systems to introduce security and traceability in different blood sample collection and analysis centers.

“…It is necessary to successfully read valuables goods with 100 % probability such as medicines, and jewelry. However, one of the key technical issues in the design of UHF near-field RFID reader antennas is to generate a sufficiently strong and relatively uniform field distribution [7][8][9][10][11][12] . In addition, low-cost commercial tag antennas are linearly polarized posing orientation sensitivity issues.…”

This paper proposes a nature-inspired spider web-shaped ultra-high frequency (UHF) radio frequency identification (RFID) reader antenna and battery-free sensor-based system for healthcare applications. This antenna design consists of eight concentric decagons of different sizes and five straight microstrip lines that are connected to the ground using 50 Ω resistors from both ends except one microstrip line, which is left for connecting a feeding port. The reader antenna design features fairly strong and uniform electric and magnetic field characteristics. Likewise, it also poses wideband characteristics by covering whole UHF RFID band (860 – 960 MHz) and tag reading volume of 200 × 200 × 20 mm 3. Additionally, it has low gain characteristics, which are necessary for the majority of nearfield applications to prevent the misreading of other tags. Moreover, the symmetric current distribution throughout the structure in this design addresses the orientation sensitivity issues associated with low-cost linearly polarized tag antennas. The measurement results show that the reader antenna can read medicine pills tagged using low-cost passive/battery-free RFID tags, tagged expensive jewelry, intervenes solution, and blood bags positioned in various orientations. As a result, the proposed reader antenna-based system is a strong contender for near-field RFID, healthcare, and IoT applications.

A Flexible and Low-Cost UHF RFID Tag Antenna for Blood Bag Traceability

et al. 2022

View full text Add to dashboard Cite

A new low-profile flexible RFID tag antenna operating in the ultra-high frequency (UHF) European band (865 MHz–868 MHz) is proposed for blood bag traceability. Its structure combines inductive and capacitive parts with nested slots allowing for the achieving of conjugate impedance matching with the IC-chip. The whole electrical parameters of the environment (substrate, bag, and blood) were considered for the design of the tag antenna. A good agreement was obtained between the measurements and electromagnetic simulations for the input impedance of the tag antenna in the UHF band. A reading range close to 2.5 m was experimentally obtained. Therefore, this tag antenna could be effective and useful in future RFID systems for blood bag monitoring, thus improving patient safety in healthcare infrastructures.
