Conductive Paint

Imagine what you could do if you could print circuits on/in notecards, inside auto body panels or on the chassis (an outdated structure in today's unibody world)... or on windows, glass, picture frames. Or on the outside of your bicycle frame. on clothing. Conductive paint implies insulative paint, sort of a primer that keeps paint from gounding out on metal and could then be overcoated to protect circuitry. May have applications where the weight of wires would be prohibitive. Of course, the paint will STILL have to connect to wires and devices, so we need conductive glue, I imagine a superglue that allows connections to modular plug-like terminals. Instead of etching circuit boards, you would screen print them. Paint COULD have the advantage of flexibility that would render conventional circuitry nonfunctional from vibration and flexure. The more I think about this, the more I think about this... I DID ask a buddy of mine that works for RayChem (folks what sell wires, etc to Boeing) about this idea, he said "oh, yeah, that's been done" But I think only in a very limited application. He couldn't really elaborate.

Thanks for reading my idea - nullman
