I'm curious if this idea is that unique -- The Exploratorium published a book called "The Art of Tinkering" in 2014 that has paper circuits that seem very similar to the authors concept.
That's the author's point -- she was working in a field where there was plenty of active work going on, but after meeting with google, the big G tried to patent it.
Well, if the Exploratorium published a book using paper circuits before Google applied for the patent, is this prior art?
