As reported by the U.S. Air Force Research Laboratory, military scientists have developed a “Terminator-like” liquid metal that can autonomously change the structure, just like in a Hollywood movie.

The scientists developed liquid metal systems for stretchable electronics – that can be bent, folded, crumpled and stretched – are major research areas towards next-generation military devices.

Conductive materials change their properties as they are strained or stretched. Typically, electrical conductivity decreases and resistance increases with stretching.

The material recently developed by Air Force Research Laboratory (AFRL) scientists, called Polymerized Liquid Metal Networks, does just the opposite. These liquid metal networks can be strained up to 700%, autonomously respond to that strain to keep the resistance between those two states virtually the same, and still return to their original state. It is all due to the self-organized nanostructure within the material that performs these responses automatically.
