The Future of Organic Electronics. ORGANIC ELECTRONICS.
Organic electronics, plastic electronics or polymer electronics, is a branch of electronics that deals with conductive polymers, plastics, or small molecules. It is called 'organic' electronics because the polymers and small molecules are carbon-based, like the molecules of living things. This is as opposed to traditional electronics (or metal electronics) which relies on inorganic conductors such as copper or silicon.
Conductive polymers are lighter, more flexible, and less expensive than inorganic conductors. This makes them a desirable alternative in many applications. It also creates the possibility of new applications that would be impossible using copper or silicon. Organic electronics not only includes organic semiconductors, but also dielectrics, conductors and light emitters.
New applications include smart windows and electronic paper. Conductive polymers are expected to play an important role in the emerging science of molecular computers.

Organic transistors are transistors that use organic molecules rather than silicon for their active material. This active material can be composed of a wide variety of molecules.
Example of an organic transistor
(on the side)
TFTs are transistors created using thin films, usually of silicon deposited on glass. The deposited silicon must be crystallized using laser pulses at high temperatures. OTFTs active layers can be theramlly evaporated and deposited on any organic substrate (a flexible piece of plastic) at much lower temperatures.
Benefits of an OTFT:
Does not require glass substrate as
amorphous Si does. It could be made
on a piece of plastic.
Manufactured at lower temperatures
Deposition techniques could reduce

FIGURES OF OFTFS
OTFT technology’s application is diverse. Organic thin-film transistor (OTFT) technology involves the use of organic semiconducting compounds in electronic components, notably computer displays. Such displays are bright, the colors are vivid, they provide fast response times (which need to be developed in OTFT), and they are easy to read in most ambient lighting environments.

Organic Nano-Radio Frequency Identification Devices
Using Nano devices researchers intend to replace the cumbersome UPC barcode that is found on many products and replace it with one of these tags. Scientists are currently working on this technology to apply it to mass checkout at supermarkets, but have several minor obstacles that still must be overcome.
Two of these obstacles are that each individual tag must cost less than one cent, and each RFID must function in the presence of substantial amounts of metal and radio frequency absorbing fluids
Meaning Of Vacuum sublimation
Vacuum Sublimation has allowed for excellent performance using small-molecule organic materials, resulting in circuits operating at several megahertz. Each nano-device will consist of 96 bits of information, but may contain more, such as 128 bits.
The operating range for low cost devices will be limited by the power delivery from the reader to each tag. This makes the lower frequencies more appealing because they are better for power coupling. Thus, 13.54MHz looks like the most attractive frequency, however researchers are also considering the frequency at the 900Mhz range also plausible.
