Don't worry, this isn't about teaching bacteria how to climb out of a petri dish and follow a subway map. The picture above actually shows an OLED display control circuit that was quickly and cheaply manufactured thanks to the joys of inkjet printing. Its makers at UCLA start-up Aneeve Nanotechnologies also claim their carbon nanotube circuit yields better performance than traditional silicon counterparts and should therefore be considered a competing technology. On the other hand, it's also true that inkjet circuitry has been around in various forms for years, so we must return to the fundamental question: will we ever be able to afford one of these?
