Statistical Analysis on Readability of RFID Gen2 Passive Tags Using Bayesian Information Criterion and 2-Level Factorial Design

RFID holds a large potential for changing how a process is manipulated and controlled. RFID is a valuable improvement in many organizations, whether it is used for monitoring logistics and supply chains, securing access within the facility or for locating and validating inventory. Most of the time, the main technical concern with RFID is whether the tags can be read in the environment they are being incorporated in. This paper examines the effect of different factors such as distance from antenna, size of tag, surface on which tag is placed, tag location & velocity/speed on the readability of a RFID tag. In this paper, we developed an effective model analysis of the factors that affect readability of RFID tag using Bayesian Information Criterion (BIC) & Design of Experiment (DOE) technique. Experiments were conducted and readings were taken to consider the effect of different factors and identify the critical factors that affect the readability, and a redundant regression model was developed using BIC. Design of Experiments (DOE) was used, specifically 2k factorial design and 2(k-1) fractional factorial design to perform statistical analysis and understand the source of variation in the model. The two designs were compared and the best out of the two was chosen to develop a model. Statistical analysis was performed using Minitab software to validate. The developed model intends to read the intensity of the tag with 97% accuracy.

RFID transponder integration in metal surgical instruments produced by additive manufacturing

Radio frequency identification (RFID) applications are becoming more and more important in logistics, especially for the purpose of tracking and managing items. Real time tracking of medical instruments during a surgical operation belongs to the state-of-the-art applications of this technology. The metallic environment in the operating room represents a big challenge, hampering the readability of the RFID tag. Currently, transponders are joined to metal instruments by bonding or clamping them inside a polymer shell, containing as little metal as possible. Assembling the tags is a time consuming process, which changes the usual shape of the instrument. It also represents a point of failure because of the possibility of losing the tag during the instrument’s life cycle. Selective laser melting (SLM) offers a way to integrate the entire RFID tag in a metallic instrument while keeping the original shape. Instrument manufacturing by SLM allows small wall thicknesses and a reduced temperature impact on the RFID tag during the building process. The production of trial components from IN718 nickel alloy is reported.

A Frequency Diverse Gen2 RFID System with Isolated Continuous Wave Emitters

The “Gen2” specification for UHF passive RFID systems released by EPCglobal has become an intense research interest. A Gen2 tag derives its power from the RF wave emitted by a Gen2 RFID reader and responds its modulated backscatter signals to the reader. Due to the large propagation loss, the accessible range of a Gen2 tag is hence limited. Moreover, the readability of a Gen2 tag is often influenced by the multipath fading problem. In order to mitigate the problems, a multi-carrier UHF passive RFID system utilizing the frequency diverse backscatter ability of a Gen2 tag is proposed in a prior work. In this work, a thorough analysis of the system is given. Especially, the appropriate powers of the transceiver and CWEs are derived to make the system more feasible in practical applications.
