Case I Electronic Paper
• Original Proposal
(with organic
transistor backplanes)
– 1996 (Bell Labs)
• First demonstration
– 2000/2001(Lucent/EInk)
• Commercial
prototypes
– Mid 2000
Case II - OFET based RFID
• First proposal
(organic FET based
RFID
– 1995 (Philips)
• Working prototypes
– 2005 to 2008
• Commercial
production

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/Vs. (Bao et al, Science 2008)
• Inorganic Semiconductors/Nanowires
– High mobilities with Indium oxide (Marks et al., Nature Materials
2006)
