Flexible electronics uses flexible plastic substrates to assemble electronic circuits by mounting devices onto flexible materials. Flex circuits consist of a flexible plastic substrate like polyimide or thin glass with a conductive path of materials like copper or graphene. Electronic components such as transistors and flexible resistors and capacitors can be made from silicon nanomembranes or thin films. Flexible displays use organic light-emitting diodes instead of backlights. Roll-to-roll processing and printing techniques are used in manufacturing. The global flexible electronics market is estimated to grow from $200 million to $800 million by 2020 with applications in automotive, space crafts, foldable displays, and military uses.
