Liquid Metal Headphones Expand To 8X Normal Length
Researchers at North Carolina State University have created conductive wires that are stretchable.
North Carolina State University researchers have created conductive wires that are less susceptible to breaking and tearing. The wires, which could be used for headphones, phone chargers, or electronic textiles, can be stretched up to eight times their original length while still functioning.
They are made using a thin tube of elastic polymer filled with a liquid metal alloy of gallium and indium, which is an efficient conductor of electricity. Assistant Professor of Chemical and Biomolecular Engineering, Dr. Michael Dickey, said:
