Researchers have developed a new type of semiconductor ink that could be used to make bendable PC screens. Researchers from Polyera Corp and BASF have developed a new semiconductor ink that is capable of carrying a negative electrical charge (N-type) - a breakthrough for the semiconductor ink industry since most semiconductor inks have only been capable of carrying a positive charge so far.

The new ink can be can be printed onto flexible materials, such as a thin film of plastic or even paper, using a modified ink-jet printer.

It would enable the creation of more complicated and useful kinds of flexible displays -- displays you can actually bend.

Being able to print electronics in much the same way as newspapers are printed could become a highly cost-effective way of printing radio frequency ID tags on a multitude of products and consumer goods, as well as opening up vast new possibilities in the world of sensor technology.

The ink, which will be on sale under the brand "ActivInk", is also easy to manufacture. The companies hope that it could be used by electronics companies working to develop devices using this new flexible, printable chip technology.
