Continuous innovation and development of advanced organic electronic technologies is likely to augment the growth of the global organic electronics market in the near future.
The need for innovative products made from non-toxic materials at an affordable price brought about disruptive changes in the electronics sector. It also catalysed the evolution of microelectronics to flexible, printed and organic electronics. Emergence of this new segment is being driven by the use of new materials and methods of manufacturing. This break from the past has provided an opportunity to countries like India who missed the microelectronics bus earlier.
According to Markets And Markets, the flexible electronics market was valued at US$ 17.85 billion in 2017. It is expected to be worth US$ 40.37 billion by 2023, at a CAGR of 11 per cent between 2018 and 2023.
IDTechEx has a much more optimistic forecast. It states that the total market for printed, flexible and organic electronics will grow from US$ 29.28 billion in 2017 to US$ 73.43 billion in 2027. This is shown in the figure below.
Majority of the flexible electronics market is OLEDs (organic but not printed) and conductive ink used for a wide range of applications. On the other hand, products such as stretchable electronics, logics and memories, and thin-film sensors constitute a much smaller segment, but with huge growth potential.
Flexible electronics allow the development of new applications by integrating intelligence in the form of electronics directly on flexible substrates such as plastics, paper, textiles or metal foils. This opens up new possibilities of developing conformal, flexible, lighter and more robust applications. The core of these applications is electronics that can be printed roll-to-roll using fast manufacturing processes, much in the same way newspapers are printed, thereby, making the products much more affordable and, if required, disposable.
Large-area flexible electronics are on the threshold of an imminent revolution that is driven by innovative applications made possible at a much lower cost than the conventional methods of manufacturing. At the heart of this revolution lie two significant capabilities: designing products that are flexible and form fitting, and their manufacturing by printing-based processes. The combination of the two may lead to roll-to-roll, large volume and high throughput manufacturing.
Organic electronics is useful for high-performance devices in four major application areas: displays, photovoltaic, lighting and integrated smart systems. These are briskly growing into a scientific and technological revolution, and are expected to have a large impact on our lives as compared to microelectronics.
Applications at a glance
Applications of flexible electronics are wide ranging and span several sectors. These include smart packages and labels for brand protection and anti-counterfeiting, wearables and lightweight electronics, distributed energy production through organic solar cells on curved surfaces, disposable sensors or lab-on-a-chip for health monitoring, flexible displays and energy-efficient lighting, among others. Major application areas are consumer electronics, healthcare, military, energy, games, logistics and automotive products.
Flexible electronics have been cited in connection with an extraordinarily broad range of product applications where bendable and stretchable characteristics offer value.
Photovoltaic panels that conform to curved or otherwise irregular surfaces offer numerous advantages over heavy and rigid panels that account for most of today’s photovoltaic electricity generation.
OLEDs can be mounted on curved and bendable surfaces to provide lighting with versatility and energy efficiency superior to conventional forms of lighting. Although OLED lighting has not been widely introduced commercially, limited-release prototypes and commercial products have become available to demonstrate their potential and allow interested users to try out OLED technology.
Flexible displays will be developed that are unbreakable, waterproof, rugged and capable of being rolled up or folded for convenience. One much discussed potential application is the ability to transform smartphones into much better computing platforms, by adding a convenient larger display that can be rolled up or folded when not in use.
Another application is flexible, roll-to-roll produced e-paper, which has already enjoyed some success on a trial basis when used to produce shelf tags for supermarkets. That said, the flexible display market has not developed commercially as quickly as had been hoped, partially due to industry restructuring and competition from tablet computers.
Sensors embedded in plastic tags are already being used in radio frequency identification (RFID) applications. Many RFID devices use antennae that are printed on flexible substrates. Sensors embedded in uniforms and other forms of clothing can be used for similar purposes.
Flexible electronics has the potential in many important applications, such as wearable health monitoring devices and medical implants. Medical patches and implants utilising bendable and stretchable sensors can potentially monitor a wide range of biological functions.
Flexible electronics technology may enable the creation of fabrics that can alter their characteristics in response to external stimuli, whether mechanical, thermal, electrical, chemical or biological.
