Article: Paper supercapacitor could power future paper electronics

(PhysOrg.com) — All those paper transistors and paper displays that scientists have been designing can now be powered by an onboard power source, thanks to the development of a new paper supercapacitor. Designed by researchers at Stanford University, the paper supercapacitor is made by simply printing carbon nanotubes onto a treated piece of paper. The researchers hope that the integrated design could lead to the development of low-cost, disposable paper electronics.

Very interesting and could lead to a lot of new and much more ubiquitous interactivity possibilities. Imagine, a circuit on your grocery bag.
