Case I Electronic Paper • Original Proposal (with organic transistor backplanes) • 1996 (Bell Labs) • First demonstration • 2000/2001(Lucent/E-Ink) • Commercial prototypes • Mid 2000
Case II - OFET based RFID • First proposal (organic FET based RFID • 1995 (Philips) • Working prototypes • 2005 to 2008 • Commercial production • Beyond 2010
Hybrid Flexible System Design • Communication • Wireless, wired • Circuit design • Semiconductor technology • Lumped silicon • Thin film semiconductors • Materials • Insulators, conductors • Other components and devices • Sensors, Actuators, display elements, etc.. • Fabrication • Roll-to-roll (RTR) or other
Thin-Film Semiconductors • Organic and Polymer • Easiest to print • Proven compatibility with R2R • Mobilities limited to near 1 cm2/V-s* • Carbon Nanotube films • Can possess higher mobilities (near 80 cm2/V-s) for L = 100 micron devices (Rogers et al., Nature 2008) • Issues of metallic nanotubes • Separation of semiconducting nanotubes yielded 0.5-0.6 cm2/V-s. (Bao et al, Science 2008) • Inorganic Semiconductors/Nanowires • High mobilities with Indium oxide (Marks et al., Nature Materials 2006)
Fabrication methods for Flexible Electronics • Ink-jet printing • Gravure • Flexo • Screen Printing • Nano-imprinting • Laser-based approaches • Photolithography for R2R
Technical Themes for the Study • Circuit and system design • Device physics • Inorganic and organic semiconductor materials for transistors • Dielectrics and conductors • Functional devices and materials (for sensors etc) • Fabrication processes
