Touch-sensitive elastic fibers could offer a new way to interact with electronic devices.
The soft, flexible fibers, developed by a team at North Carolina University, are made up of polymer strands filled with a liquid metal alloy of eutectic gallium and indium (EGaln). Each fiber is made from three strands, with each strand containing a different amount of the liquid metal alloy. When the fiber is touched, the capacitance between the fingertip and the EGaln within the insulating strands will vary based on the number of strands containing the metal alloy in a particular section of the fiber, allowing the touch to be translated into a command.
