PLASTIC ELECTRONICS
Plastic electronic is an internationally networked technology company which develops, produces and markets products with intelligent multi-layer surfaces.These products are based on multiskin, a trademarked technology developed by plastic electronic. Similar to touch skin, multiskin sensors and characteristics are hidden underneath its surface. Just like skin, multiskin is robust and flexible for full design freedom.
v Touch skin
It is a touch-sensitive intelligent surface which completely replaces mechanical switches, sliders and wheels with capacitive electronics.touchskin can be combined with any moulded surface and also other materials like wood or fabric. And it can be shaped in any 3D surface, opening up an entirely new world of design freedom. Its seamless surface makes touchskin devices dirt- and water-resistant with low wear and abrasion.

Carbon nanotube films for transparent and plastic electronics
A two-dimensional network – often referred to as a thin film – of carbon nanotubes can be regarded as a novel transparent electronic “material” with excellent – and tunable – electrical, optical and mechanical properties. The films display high conductivity, high carrier mobility and optical transparency, in addition to flexibility, robustness and environmental resistance
Eg for carbon nano tubes

silicon processing requires temperatures above 1000 °C and clean room conditions, “plastic electronics” merely require room temperature. Comparatively speaking, the manufacturing methods are environmentally friendly and save resources. In contrast to the current time-consuming and thus expensive technology, organic semiconductors can be mass-produced at a low cost. The availability of raw materials is practically unlimited. In a wafer-thin layer, the electronic components can be applied to the different carrier materials. They easily and flexibly adapt to surfaces, requiring only little space, and are virtually unbreakable. It is even possible to produce coatings with ink-jet printers using electronic ink or with classic printing methods. A complete test printer already exists. It is possible to print transistors, LEDs, solar cells, sensors, batteries and displays. Another option is to integrate barely visible electronic circuits into fabrics and wallpapers.
The technology has already reached market maturity and is used efficiently with organic LEDs (OLED). Low degrees of efficiency of about 8 % suggest even more potential: transparent films with solar cells on mobile phones, laptops and other mobile devices could considerably extend battery life. Besides marketable RFID chips and price tags, a team of researches has even created microprocessors that are made of polymer films. The first organic lasers for optical measuring and for batteries have left the research lab. With the consistent refinement of organic electronics, numerous application possibilities for everyday use will arise..
Organic Electronics
Organic Electronics is a new field of electronics in which the structures that are used are based on organic materials: dielectric, conductive or semiconductor polymers or small organic molecules deposited mainly on flexible substrates
Organic semiconductors offer a low cost alternative to
established semiconductors when it comes to large area and low cost applications .It provides new materials to build next generation electronics and photonics devices. With a focus on organic semiconductors and dielectrics, these materials will enable the creation of products for:
Organic Thin Film Transistors (TFT) – notably for radio frequency identification (RFID) and display backplanes.Although these materials may be applied by a variety of techniques including evaporation and thermal transfer, they are primarily designed for solution processing of creating organic electronic (OE) systems. The advent of high-volume, cost-effective OE print manufacturing technology will allow manufacturers of OE products to turn their existing materials into “inks” for printing.
Two different groups:
- Small molecular meterials
mainly prepared by thermal evaporation
eg
Pentacene Anthracene
Anthracene
- Polymers
prepared by solution processing (spin-coating, inkjet printing)
eg:-
Polythiophene (PT)
Polyphenylen-vinylen (PPV)

Organic Thin Film Transistors
- Possible use in active matrix flat panel displays,electronic
paper” displays, sensors or radio-frequency identification
tags
- In competition with a:Si:H which is normally used in active matrix displays
Polycrystalline Pentacene
When diffusing from one grain to another, charge carriers get scattered at the defects introduced by the grain boundaries. These boundaries hence reduce the effective mobility.
Organic Photovoltaic Cells
Photovoltaic effect in single layer organic molecules first observed in the 1970s, later on also for polymers Cells consisting of a single material reach only very low efficiencies ! combination of at least two materials necessary
Advantages of organic electronics
- The possibility of manufacturing components and circuits over large areas, while silicon chips are restricted to the area of circular pads of limited sizes.
- It can be fabricated on plastic substrates, thin and flexible.
- Only the flash memory transistor, the silicon component found in the pen-drives in digital cameras and MP3 players, continued to resist the benefits of plastic.
The low electrical conductivity is a disadvantage and currently limits possible applications. Research and development of new polymer combinations to increase conductivity cost money and time. There is also too little detailed evidence on long-term durability.
