Flexible electronics is a technology for building electronic circuits by depositing electronic devices on flexible substrates such as plastic. In the simplest case, flexible electronics can be made by using the same components used for rigid printed circuit boards. The only thing that needs to change is the substrate, being made flexible, rather than rigid. Typically, in LCD fabrication for example, glass is used as a substrate. If thin flexible plastic or metal foil is used as the substrate instead, the entire system can be flexible, as the film deposited on top of the substrate is usually very thin, on the order of a few micrometres.

OLEDs are normally used instead of a back-light for flexible displays, making a flexible organic light-emitting diode display. An organic light-emitting diode (OLED) is a light-emitting diode (LED) made of semiconducting organic polymers. ... A flexible organic light-emitting diode (FOLED) is a term used for a flexible OLED. While OLEDs might commonly be applied to sturdy panels, such as glass, a FOLED is the same thing built on a flexible substrate. ...


Flexible solar cells have been developed for powering satellites. These cells are lightweight, can be rolled up for launch, and are easily deployable, making them a good match for the application. A solar cell, or photovoltaic cell, is a semiconductor device consisting of a large-area p-n junction diode, which in the presence of sunlight is capable of generating usable electrical energy. ... A satellite is any object that orbits another object (which is known as its primary). ...


Flex circuits are often used as connectors in various applications where flexibility, space savings, or production constraints limit the serviceability of rigid circuit boards or hand wiring. In addition to cameras, a common application of flex circuits is in computer keyboard manufacturing; most keyboards made today use flex circuits for the switch matrix. A camera is a device used to take pictures (usually photographs), either singly or in sequence, with or without sound recording, such as with video cameras. ...

Thinking Small (6375 words)
This is the gap between the valence band of electrons surrounding an atom (those electrons that are part of the material's elemental structure) and the conduction band of electrons that flow in the presence of voltage.
Having one electron, because it is easy to control, has expedited research into the new field of spintronics (electronics based not on an electron's charge, as in a traditional transistor, but on its spin) and into the development of systems for quantum information processing.
Flexible electronics, which allow the fabrication of "cheap and powerful displays with the properties of billion-dollar fabrication-line silicon," says Lieber, are easy to make and of high quality.
