Tutorial : The Design of Passive Integrated Single-Chip RFID and Sensor Systems

Instructor: Prof. L. Richard Carley Carnegie Mellon University

Time: Sep.21 14:50~15:35

Abstract: This tutorial begins with a discussion of the cost, size and ruggedness advantages that passive integrated single-chip RFIDs and sensor systems can offer and some potential application areas for such devices; e.g., RFIDs for pills and implanted biomedical sensors. The design of passive integrated single-chip RFIDs and sensor systems, ones in which the antenna and the RFID circuitry are all fabricated on the same integrated circuit substrate, is challenging because the small size of the antenna and its proximity to a resistive ground plane (the integrated circuit substrate) both decrease the RF energy that can be harvested to operate the RFID or sensor system.  In this tutorial, we will make simplifying approximations in order to develop basic equations relating the size and geometry of the antenna to the ability of the RFID system to harvest energy; and, we will validate those equations with electromagnetic field simulations. The tutorial will consider operation across a range of frequencies and will explore both in-plane spiral antennas, the use of insulating substrates, and the use of out-of-plane helical antennas. We will also explore the challenging issue of matching the antenna to on-chip electronics both for maximizing power transfer and for mitigating the losses due to the turn-on voltage of whatever rectifier circuits are used.  At the circuit level, we will explore techniques for anteann impedance matching and advanced rectifier circuit designs that can operate on smaller antenna output voltages.  Finally, we will explore ways in which Microelectromechanical Systems (MEMS) wafer-scale fabrication techniques can be applied to improve the power transfer to passive integrated single-chip RFID and sensor systems. We will conclude the tutorial by showing examples of MEMS sensors that can also be fabricated in using MEMS wafer-scale fabrication techniques in order to create passive single-chip RFID and sensor systems.

Tutorial : Printed Electronics and RFID

Instructor: Dr. George Xiao, National Research Council, Canada

Time: Sep. 21 15:35~16:20

Abstract: Printed electronics is using the printing techniques, such as flexography, gravure, inkjet, offset lithography and screen printing, to create electronic devices. It is an emerging technology and can be used to fabricate simple and low cost devices on any solid substrates such as paper, plastic, rubber, fabrics and etc. This makes printed electronics ideal for the fabrication of RFID inlays, and devices for wearable, IOT and disposable medical diagnosis applications.

This tutorial begins with the introduction of the printed electronics technology, its advantages and disadvantages and its major applications. The operation principle and procedures of printed electronics process are explained using the screen printing as the example, as it is the most mature and the most widely used printed electronics technique.

Antenna is the most critical part of a RFID tag or reader. The tutorial will discuss how to fabricate high quality RFID antennas for various applications using the screen printing technique. The challenges and the solutions will be presented in the tutorial using the real cases as the examples, including the HF antennas for ID, wireless power transfer applications, and the UHF reader antennas.

How to print other RFID components will also be presented in the tutorial, such as the battery, memory and sensors. Future directions in using printed electronics to create RFID based products will be discussed in the last part of this tutorial.

Keynote : Advanced Antennas for RFID Tags and Readers

Presenter: Prof. Zhi Ning Chen,National University of Singapore

Time: Sep. 21 16:20~17:05

Abstract: Radio frequency identification (RFID) technology are being rapidly developed in recent years and the applications have been widely found in Internet of Things (IoT) such as service industries, distribution logistics, manufacturing companies, and product-flow systems. Antenna design for readers and tags is one of the key factors in RFID systems. The optimized tag and reader antenna design will greatly benefit to RFID systems with longer reading range, better detection accuracy, lower fabrication cost, and simple system configuration and implementation. This talk will start with a brief introduction to RFID systems which may be active, passive, or semi-active systems, and operate at LF, HF, UHF, or MW bands. Then the key considerations related to the antenna design for tags and readers will be addressed from system perspectives. After that, the advancement of RFID antenna designs by the team from Institute for Infocomm Research/Singapore National University of Singapore will highlight specific challenges for antennas in the HF near-field and UHF near/far-field systems. In particular, important engineering factors such as environmental effects vs. co-design methodology, size constraints, cost constraints, and UHF near-field reader antenna coverage will be presented with corresponding practical design cases.
