Printed electronics is an emerging and innovative field that holds tremendous potential for reshaping various industries. By replacing rigid silicon chips with flexible circuits and components printed directly onto substrates using techniques such as inkjet printing, screen printing and others, it enables the fabrication of electronic devices and systems in new form factors that were not previously possible. This promising technology is poised to make electronics more affordable, ubiquitous and integrated into everyday objects.
What are Printed Electronics?
Printed electronics refer to electronic devices and circuits that are formed by printing of thin-film materials such as semiconductors, insulators and conductors onto various substrates using printing techniques. The most common printing methods used are inkjet printing, gravure printing, screen printing and flexographic printing. These printing processes allow for the deposition of functional inks made of materials like organic semiconductors, nanoparticle inks, carbon nanotubes and more in an inexpensive, high-speed roll-to-roll or continuous production manner.
The key advantages of printed electronics over conventional silicon-based electronics are flexibility, low cost, large-area deposition and integration with novel substrates. Since printing enables the direct fabrication of electronics onto various surfaces without the need for expensive semiconductor manufacturing equipment and processes, it is ideal for creating lightweight, flexible, low-cost electronic systems in rollable displays, smart packaging, wearable devices and more.
