Printed electronics belongs to a “modern” field of electronics with a set of printing methods/ technologies used to create electronic devices on various substrates i.e. rigid (Glass, etc.), flexible (PET, Kapton, PEN, PC, etc.) and recently stretchable (PDMS, thermoplastic PU) substrates. Printing typically utillises common printing equipment suitable for defining patterns on material, such as screen printing, flexography, gravure, slot-die, offset lithography, and inkjet. Compared to conventional electronics industry and the devices fabricated, these are low cost processes. Electrically functional electronic inks are deposited on the substrate, creating active or passive devices, such as thin film transistors; capacitors; coils; resistors, photovoltaics, thermoelectric generators, OLEDs, etc. The term printed electronics is often related to organic electronics (OEs) or plastic electronics, in which one or more inks are composed of carbon-based compounds. These other terms refer to the ink material, which can be deposited by solution-based, vacuum-based or other processes. Printed electronics, in contrast, specifies the process, and, subject to the specific requirements of the printing process selected, can utilize any solution-based material. This includes organic semiconductors, inorganic semiconductors, metallic conductors, nanoparticles, and nanotubes. The most important benefit of printing is low-cost volume fabrication. As such, printed electronics is expected to facilitate widespread, very low-cost, low-performance electronics for applications such as flexible displays, smart labels, decorative and animated posters, and active clothing that do not require high performance.
