Sometimes, people may need to use earphones, mobile phone chargers, or data cables at a great distance, but their length is relatively fixed and cannot be extended. The solution is to add extra extension cords. However, researchers at North Carolina State University in the United States have recently developed a liquid metal wire that can be flexibly retracted to a maximum of 8 times its original length. This will make it easier for people to use the above electronic wire equipment. Previously, scientists have begun to study electrically conductive metal wires with retractable properties by adding metal particles in a hollow, stretchable fiber tube, but wires made using this method are less flexible or less flexible. The new researched elastic wire uses a similar method, except that the internal conductive metal is replaced by a gallium-indium liquid alloy, which enables the new wire to maintain good electrical and mechanical properties when stretched. It is also much longer than the pipeline filled with metal particles. Of course, this liquid metal wire also has its drawbacks. Michael Dickey, an assistant professor at North Carolina State University who is one of the researchers, said that this liquid metal can quickly oxidize into solids and fill the small leaks. But if a curious child deliberately chews this liquid metal wire, they still have no way to prevent potential metal leakage or metal swallowing.
