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 presentation 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 presentation 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 presentation, 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 presentation.
