The mass production of flexible, printed electronic circuits could now be a reality thanks to boffins who have figured out a way to shoehorn liquid metal into an inkjet printer. By subjecting a gallium/indium mix to ultrasound, material scientists at Purdue University turned liquid metal into nanoparticles small enough to be printed like ink. Keep up!

Theoretically, liquid metal circuits will be able to withstand stretching, squeezing and folding; opening up a whole new field of robotic possibilities – pliable robots that can squeeze through holes and stretchy embeddable medical devices will  both be feasible. As would the T-1000 liquid metal robots from Terminator 2…
