Wearable Monitors

This is very cool! Imagine a classroom where the curtain is your display - or a paper thin, flexible Kindle-like device.

Technology Review: Stretchable Displays:
Researchers at the University of Tokyo have moved a step closer to displays and simple computers that you can wear on your sleeve or wrap around your couch. And they have opened up the possibility of printing such devices, which would make them cheap.

Takao Someya, an electrical-engineering professor, and his colleagues make a stretchable display by connecting organic light-emitting diodes (OLEDs) and organic transistors with a new rubbery conductor. The researchers can spread the display over a curved surface without affecting performance. The display can also be folded in half or crumpled up without incurring any damage.

Combined with printable transistors and OLEDs, this could pave the way for rolling out large, cheap, wearable displays and electronics.

Bendy, flexible electronics that can be rolled up like paper are already available. But rubber-like stretchable electronics offer the additional advantage that they can cover complex three-dimensional objects.
