There is a whole industry trying to print electronics - the idea of using conventional printing processes to make low cost, thin and flexible electronics components from batteries to e-paper-like displays, solar panels or sensors. Printoo makes some of these new technologies accessible to anyone on Kickstarter, in a modular form factor that allows users to easily create their ideas with it.
There is, of course, a trade-off about making it modular - you need solid connectors and you make it larger - but the idea is for Printoo to be a tool to create first product concepts, and start to generate the ecosystem for makers to then go on to take the second step and create use-specific prototypes.
Printed Electronics will allow to add intelligence/computing to a lot more objects/substrates than conventional rigid electronics - smart credit cards, posters, packaging, wearables, medical patches, playing cards, board games, labels, stickers. To bring these ideas for future applications in ubiquitous computing/internet of things, you need the prototyping tools to start playing with the right technologies for that, and for that we had to compromise on size and bulkiness in favor of modularity and accessibility.
