The concept of functional printing refers to print with inks with special features such as biosensors and thermochromatic.

In the case of functional printing, the ink has the functionality itself, while in printed electronics an electronic component is formed by interactions that are generated by the deposition of different layers.

However, it also can be manufactured components or modules that are not electronic and nano-lenses or micro sieves.

With printing processes it is possible to produce luminescent components such as OLEDs (organic light-emitting) organic polymer solar cells (OPVC), RFID antenna, biosensors and more. The combination of the different components makes it possible to make smart packaging or smart cards with different functions, for example, prevent counterfeiting or simply add a luminescent element to serve as an advertising medium which exhibits the brand.

Comparison between graphic printing and functional materials printing

In the market there are several products like bags with integrated wireless modules, OLED lamps or OLED screen phones. As printed electronics is part of organic electronics, it can not be distinguish whether the products are manufactured by printing processes or if materials are deposited by other processes such as centrifugation or thermal evaporation.

According to a study by IDTechEx Ltd. consultants of England this market will grow from 1.9 billion USD in 2009 to 57 billion dollars in 2019.
