Printed electronics companies are currently working in fields ranging from: smart credit cards (with auth codes for instance), medical patches, interactive packaging (in the Harry Pottery sense but also for sensing), interactive playing cards, children's books and board games (also Harry Pottery), smart labels for logistics purposes, stickers, control panels in automobiles and other circumstances where you may have a non-flat surface.

There's a lot of interesting work being done on the flexible board technologies themselves. AgIc and others are supplying the tools for personal fabrications of flex circuits. It's way cheaper today to prototype using inkjet printed copper on PET than normal PCBs.

Finally, there is a little distinction between traditional FPC technology, where discrete components are placed on a kapton-based film, and printed electronics technologies, the idea of producing electronics components ranging from transistors, batteries, displays, memory, antennas or sensors. Printoo uses a hybrid approach since Printed Electronics are not yet mature enough to provide the full solution.

Sorry for the lengthy reply!
