Motherboard : A newly developed electronic material can stretch up to four times its original length. It comprises gallium nanowires encased in gold and patterned onto a thin polymer film. Stéphanie Lacour of École Polytechnique Fédérale de Lausanne in Switzerland and her colleagues chose gallium for its electrical properties and low melting point, which allows it to remain liquid at room temperature. The gold lowers the surface tension of the gallium, preventing it from separating into droplets. The material could have a number of applications, such as artificial skin for prosthetic limbs.
