Flexible Electronics: Emerging Trends


Dr. Narayanan Unni on 21st January 2014 at 11:30 am

Flexible large area electronics is a segment of electronics which is based on the monolithic integration of electronics on amorphous substrates which have large dimensions. This can be seen in contrast to conventional microelectronics involving monolithic integration of electronics on crystalline substrates which are much smaller to make integrated circuits (ICs) or individual devices. In large area electronics, there is an imminent revolution that is driven by innovative applications at a much lower cost than conventional methods of manufacturing.  At the heart of this revolution are flexible and form fitting property of products and their manufacturing by printing based methods.  The combination of the two will lead to manufacturing that is on a roll-to-roll basis. The electronics emerging from this would be on substrates that are plastics, paper, textiles or metal foils.  The circuits will be printed roll-to-roll for fast manufacturing processes, much the same way as newspaper printing.  The products will be much more affordable and even disposable, where needed.  They find applications in several industry sectors including distributed energy production through organic solar cells on windows and roofs, disposable sensors for air and water quality management or lab-on-a-chip for health monitoring etc. The first half of the talk will give ideas about the market projections about flexible and printable electronics and interesting applications. The second half will deal with different printing techniques and processes and materials requirements involved in large area printed electronics.
