Embedded tech can fit into some incredible spaces, but it can't yet fit everywhere; there are places that are simply too harsh or small for modern technology. If GE gets its way, though, just about any surface will be fair game. Its Direct Write technology uses ink made from either metals or metal oxides to print tiny, flexible sensors that both fit into tight spots and survive conditions that typically fry electronics. You could see sensors inside the hot environment of a jet engine, or put both pressure and temperature sensors into areas that normally don't have room for anything.
