Research Experience for Undergraduates Final Report “Development and Design of Printed Electronics with Focus on RFID Systems for Transmission of Data and Impedance Variance Sensors” By: Federico Diamante and Robert Donatto Advisor: Dr. Thomas Weller National Science Foundation (Award #0851973)
Research Experience for Undergraduates Outline Background Problem Statement Objective Methodology Equipment 3-D Printer parts Solutions/Results Future Works Special Thanks Questions National Science Foundation (Award #0851973)
Background • Why Printed? • Fast prototyping • Does not require expensive equipment • Malleable • Time consuming, requires expensive equipment, made on rigid substrates.
BackgroundNew Technique Dilemma • Nano Ink • Silver as conductor • Variety of nanoparticle size • Conductivity • Paper substrate • Different papers • Change in dielectric properties • Absorption • Printer • Printer resolution HindenburgIncident
Background Printing Issues • Printing with conductive inks • Precision • Printer DPI • Curing (Vacuum Oven) • Substrate absorption
Background Conductivity Issues • Nano sized silver particles • Conductivity • Resistivity • Curing • Malleability
Problem StatementLow Cost Approach • Printing antennas and sensors with inkjet printer • Must use off the shelves printer • Minimum production process • Low cost substrate • Paper • Use of conductive inks • Copper (Ground) • Silver (antenna/sensor) • Must be malleable • Bendable • Flexible
Objective • Printing antennas on paper • Development of antennas of non traditional emission antennas • RFID tags • Sensors
Methodology • Prepare Ink Cartridge • Prepare Silver particle Ink Sample • Prime and Fill Cartridge • Design Antennas on ADS software • Develop premade calculations • Apply real world calculations in simulations
Methodology • Scanning Electron Microscope (SEM) • Able to detect potential “cracks” in sample • Captures images on the scale of nanometers
Equipment DC Power Supply: Supplies multiple outputs to a single unit VNA: (Vector Network Analyzer) Used for measuring amplitude and phase properties Ink Jet Printer (Epson R2000):Used for printing conductive ink onto various flexible substrates Multimeter: Measures voltage, current, and resistance Silver Particle Ink: (75nm)Conductive ink used to print electronic components SEM: (Scanning Electron Microscopy) Used for surface imaging of the sample Ink Jet Cartridge: Cartridge used to hold silver particle ink.
3-D Printer Parts • 1.Sanguino- Processor for delivering instructions to 3-D printer • 2. Motor controls- Controls the X, Y, and Z coordinates of the printer • 3. Step motors (3) – Used to move fluid dispenser across X, Y, and Z coordinates • 4. Air Regulator- Controls amount of fluids deposited across the surface • 5. Fluid Dispenser – Ejects fluid onto surface 3 5 1 4 2
Proposed Solution /Results A B C D E F • Minimize width, maximize resistance
Proposed Solution /Results • Test length about 500mm
Proposed Solution /Results • Silver Ink Particles • Current Particle Size of Ink is roughly 75nm • Gather materials to create smaller particle sized ink • (5,20,30nm)
Proposed Solution /Results • Printed Electronics (RFID tag) • Loop AntennaADS simulations
Future Works • Printed Electronics (RFID tag) • Archimedean Spiral Antenna & Dipole Antenna • Orient one antenna on X-axis, and other on Y-axis • High Bandwidth • Circular polarization • High efficiency • Sensitive to RF fields • Null condition • Perpendicular antennas: • 2nd antenna picks up the other antenna’s null areas • High degree of orientation insensitivity
