1. “Development and Design of Printed Electronics with Focus on RFID Systems for Transmission of Data and Impedance Variance Sensors” Federico Diamante, Robert Donatto, VinicioCarias, Michael Grady , Dr. Thomas WellerElectrical Engineering: Wireless and Microwave Information Systems Group (WAMI) Abstract Methodology & Equipment Future Work Electronic circuits are costly and time consuming to manufacture. However, the future of printable electronics looks promising with the ability to develop state of the art electronics at a reasonable price efficiently. The purpose of this research is to investigate alternative ways to produce reliable and inexpensive integrated circuits. Various developmental testing consists of using silver nano-particles (also called quantum dots) submerged on a water base solution ink to be printed via ink jet printers. The silver print will act as transmission lines between components as well as the conductive material for intricate antenna designs. Our current research consists of testing materials for accurate design on different CAD software, with a short term goal to simulate and construct different types of circuits. While our long term goals include the design and construction of a three-dimension printer that will incorporate the production of the substrate as well as the printing of an embedded circuit. The printed electronics technology is a new and untested territory and there is some research being done on the development of sensors and antennas and our goal is to expand the knowledge and to test its boundaries. Current design concepts will be focused on a RFID tag which can transmit data via printed antenna. The future of printed electronics will be an on demand instant delivery of any products that employ electrical components. In the future a printed electronics technology will allow the manufacture of electronic devices such as television or personal computer, all from a small work station from the home or office. • Developing and programming 3-D printer. • Build a three axis printer based on Sanguino(Arduino platform) and step motor controllers • Designing perpendicular diverse antennas. • Archimedean Spiral Antenna & Dipole Antenna on ADS. • Orient one antenna on X-axis, and other on Y-axis. • Generate a 3-D printed antenna. • 2nd antenna picks up the other antenna’s null areas • High degree of orientation insensitivity • Implement antennas with RFID tag to transmit data to RFID reader • High Bandwidth • Circular polarization • High efficiency Silver nano-particles dissolved in water solution Empty ink cartridges Empty ink cartridges are filled with Silver ink Cartridges are inserted on Epson R2000 printer 3D Printer parts [2]3D Printer • Since printing electronics requires the use of a special type of ink, certain preparations must be done to insure proper functionality that the ink-jet printer is printing silver ink.
