3-D structures built out of metal

     Researches have developed three dimensional structure out of liquid metal. Dr.Michael Dickey " It is difficult to create structure out of liquids,because liquids wants to be ads up.But we have found that a liquid metal alloy of gallium and indium reacts with oxygen in the air at room temperature to form a 'skin'that allow the liquid metal structure to retain the shape"
             The researchers developed multiple techniques for creating these structure ,which can be used to connect electronic components in three dimensions .white it is the relatively straight forward to pattern the metal "in plane". The meaning of in plane is all on same level.These liquid structure can also from shapes that reach up or down.
            One technique involves stacking droplets of liquid metal on top of each  other ,must like a stack on oranges at the supermarket. Another technique injects liquid metal into polymer templates, so that the metal takes in a specific value.
