Flexible electronics, based on plastic transistors are receiving tremendous interest because they offer a simple and economical alternative to current IC manufacturing, while opening the door for exciting new applications like flexible displays. Significant strides are being made in developing simple printing techniques such as ink jet printing and screen-printing for polymer electronics and the technology currently stands at the cusp of a revolution in electronics manufacturing. Baverstam explores some of the latest developments in flexible electronics with particular emphasis on the printing methods used in their production. An update on new plastic electronics materials is also provided, which are estimated to address a potential market of over $300 billion or twice that of silicon electronics. Finally, it takes a look at important new applications enabled by flexible electronics and report latest product developments in this area.
