An 8b organic microprocessor on plastic foil

We introduce a microprocessor made by organic thin-film transistors processed directly onto flexible plastic foil. This is a direct realization of a microprocessor by thin-film technology, i.e., without transfer, on plastic. It paves the way to equip mundane supports and objects with low-cost computing power. We also demonstrate the correct...

Circuit design in organic semiconductor technologies

In this paper, we review the state of the art of digital and analog circuits that have been shown in recent years in organic thin-film transistor technology on flexible plastic foil. The transistors are developed for backplanes of displays, and therefore have the characteristics to be unipolar and to possess two gates. The dual-gate architecture...

Towards EPC-compatible organic RFID tags

In this chapter, fully integrated organic RFID tags are demonstrated. These tags are inductively-coupled at a base frequency of 13.56 MHz and can be read out at distances up to 10 cm, which is the expected readout distance for proximity readers. We also demonstrate next generation transponder chips, fabricated in a dual-gate technology. The...

Organic transistor technology options for device performance versus technology options for increased circuit reliability and yield on foil

Last year, advances in organic device technology (such as device scaling, high K-dielectrics [1], ... ) enabled a substantial progress in performance. This resulted in an increase in the data rate of plastic transponder circuits from about 2 kbit/s [21 to EPC-compatible speeds (SO kbit/s). The organic semiconductor pentacene deposited from...

Organic RFID transponder chip with data rate compatible with electronic product coding

Data rates of plastic transponder chips have been limited to a few kHz, limited by the inherent low mobility of organic semiconductors. However, a target application for plastic RFID tags is Electronic Product Coding (EPC), which will require, at a base carrier frequency fc = 13.56 MHz, a data rate of fc/512 = 52.969 kb/s. In this work, we show...

Robust digital design in organic electronics by dual-gate technology

Research towards organic RFID tags is one of the drivers of organic electronics. In recent years, 64b organic RFID tags have been shown with capacitive coupling [1] and inductive coupling at 13.56 MHz [2,3]. Recent improvements were a 128b organic transponder chip with basic anti-collision and Manchester encoding [4] and a first 4b tag in...

Towards EPC compatible plastic RFID tags

A target application for plastic RFID tags is Electronic Product Coding (EPC). The EPC-specifications set some demanding requirements for RFID tags. In this work, we review the work that has been done to fulfill some of these specifications. We describe a complete 64-bit RFID tag that is inductively-coupled at a base carrier frequency of 13.56...

Plastic circuits and tags for 13.56 MHz radio-frequency communication

We discuss the design and implementation of 64-bit and 128-bit plastic transponder chips for radio-frequency identification tags. The 64-bit chips, comprising 414 organic thin-film transistors, are integrated into fully functional plastic radio-frequency identification tags with 13.56 MHz communication. The required supply voltage on the tag is...
