Printed, Flexible and Organic Electronics is one of the fastest growing technologies in the world.
It is of vital interest to industries as diverse as consumer goods, healthcare, mobility, electronics, media and architecture. The sector comprises of a diverse range of enabling technologies at different stages of commercialization.
Flexible electronics have recently attracted much attention since they enable many promising applications such as RFID tags, solar cells ,bio-sensors, wireless power and signal transmission sheets ,e-skin, e-paper and flexible display. The characteristic of flexible electronics is not only reduced cost and they have light weight, thinner, non-breakable & new forms to create many new applications. It is an attractive candidate for next-generation consumer electronics and they will soon be part of our daily lives. Development strategy of flexible electronics is dependent on global technology progresses and market forecasts. Currently, it has been estimated that there are about 1500 worldwide research units working on various aspects of flexible electronics.
Flexible electronic devices fabricated on plastic substrate are more desirable than rigid counterparts for future displays, lightings, or solar cells. For flexible electronics to become practical, the indium-tin-oxide (ITO) electrode should be replaced due to its brittleness, increasing cost, and chemical instability. Graphene has emerged as a promising material for flexible transparent conducting electrodes because of its unique electronic and mechanical properties with high optical transmittance. Therefore, graphene has been widely used in flexible electronic devices including light-emitting diodes (LEDs), solar cells (SCs), and field-effect transistors (FETs).
