GE's metallic ink can put tiny sensors inside jet engines

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.

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.
