Flexible Electronics

Flexible electronics are attractive techniques which are believed to be widespread and occupy huge market. Flexible electronics, which can maintain functionality when subject to a large deformation or stress, represent an important direction of future electronics, manufacturing and mechanical engineering. Wearable, rollable and foldable displays, Sensors, solar cells, batteries and other flexible electronics/devices will bring us completely different user experience and even change our daily life.

Several strategies have been developed to make flexible and stretchable electronics/devices. For example, one approach is to use organic conductive or semiconducting materials, or inorganic thin films or one dimensional nanomaterial that can flex. Recently, several printing techniques, including inkjet printing, nanoimprinting and screen printing, have emerged as a very promising technical trend to produce flexible and stretchable electronics/devices.

There is increasing demand for high quality and low cost electronic components such as RFID tags, thin film transistor, super capacitor, flexible sensor and devices, which require innovative fabrication techniques that are faster but cheaper compared to traditional production methods. It is also predicted that the market of flexible organic and printed electronics will exceed $300 billion by 2028.

Flexible electronics is no longer just an experimental technology. Today it can be seen to offer multiple possibilities and it has great potential, in that it gives new functions and differential properties to many products that are already on the market. Among its characteristics are flexibility, ease of integration, adaptation to widely differing environments, cost and scalability to large formats.
