Flexible electronics is still considered by some to be a relatively new technology and is also much broader in its scope than the current general market understanding. It is the fastest growing technology, partly due to it permitting solutions and product designs that older generation electronics cannot.

Flexible electronics is also one of the key enablers of 5G, a market that is expected to reach over $720 billion by 2030 thanks to large scale roll-out of infrastructures and rapid adoption of 5G devices and services. 5G is set not only accelerate the growth and expansion of telecoms along with digital communication but is set to redefine and accelerate growth across multiple industries, and flexible electronics will make that possible.

Today, many companies already turn to flexible electronics to gain a competitive edge, or to provide solutions to complex design and fit problems; for it enables smaller, thinner, contoured, flexible, formable, lightweight product designs, and provides a greater level of sustainability.

Current Definitions

Despite the increasing application of flexible electronics, how this technology is defined today simply does not do justice to the significant opportunities you gain in both product functionality, design, look and feel.

Wikipedia defines flexible electronics as: “Flexible electronics, also known as flex circuits, is a technology for assembling electronic circuits by mounting components on flexible substrates, such as polyimide, PEEK (Polyether ether ketone) or transparent conductive polyester film. Additionally, flex circuits can be screen printed silver circuits on polyester.  Flexible electronic assemblies may be manufactured using identical components as those used for rigid printed circuit boards, allowing the board to conform to the desired shape, or to flex during its use. An alternative approach to flexible electronics suggests various etching techniques to thin down the traditional silicon substrate to a few tens of micrometres to gain reasonable flexibility, referred to as flexible silicon”.

Although the basic principles are correct, this Wikipedia definition omits significantly expanding areas of flexible electronics due to its focus on circuitry and plastic or polyester substrates. Flexible electronics is not necessarily just circuits, as demonstrated by products such as flexible displays and sensors. Substrates for flexible electronic circuits can be far more diverse than just plastic or polyester; the circuit can be woven from electronic textiles, and organic material including human skin can be used. With many aspects not captured, it is merely an outdated description referencing a small part of what flexible electronic circuits are, or were considered to be historically.

Another example is from IDTechEx, a leading emerging technology independent market research firm, who state: “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”. This definition has been broadened to include “a diverse range of enabling technologies”.

Whilst broader technology examples are omitted, they report that flexible electronics is a fast-growing technology, and forecast that the market for printed electronics, including organics, inorganics and composites will rise from $31.7 billion in 2018 to $77.3 billion in 2029.

Many reports and articles can be found as to what flexible electronics is, but most often they lack critical definition and explanation as to the endless opportunities this technology offers.
