Beyond sci-fi: Manipulating liquid metals without contact: Look Ma. No hands!

Research inspired by Terminator 2’s shape-shifting, liquid metal robot sees liquid-metal electrical conductors manipulated in mid-air without contact. The liquid wires can be controlled to move in any direction, and manipulated into unique, levitated shapes such as loops and squares using a small ‘triggering’ voltage and a magnet. The new technology has potential application in advanced manufacturing and dynamic electronic structures, augmenting other non-contact manipulation technologies such as acoustics or optical tweezers.
