Imagine owning a television with the thickness and weight of a sheet of paper. Some day in the near future, it will be possible, thanks to the growing field of printed electronics.
The process, which allows manufacturers to print or roll materials onto surfaces to produce an electronically functional device, is already used in organic solar cells and organic light-emitting diodes (OLEDs) that form the displays of cell phones. Batteries, antennas, memories, sensors and other electronic components can also be printed.
