New method uses soft sheets made of silicone rubber that have many tiny droplets of liquid metal embedded inside them (scientificamerican.com)
To fabricate the wires, the scientists employed a procedure known as the self - catalysed Vapour - Liquid - Solid (VLS) method, in which tiny droplets of liquid gallium are first deposited on a silicon crystal at a temperature of around 600 degrees Celsius. (sciencedaily.com)
It prevents droplets of the liquid from making physical contact with the surface, causing them instead to hover over the surface. (sciencedaily.com)
