One of the methods that the researchers developed involves stacking droplets of liquid metal on top of each other, much like a stack of oranges at a supermarket. These droplets adhere to one another, but retain their shape rather than merging into a single, larger droplet. Another technique involves injecting liquid metal into a polymer template so that the metal takes on a specific shape. The template is then dissolved, leaving behind only the liquid metal.
