A rewritable liquid metal circuit board demonstrates dynamic connections formed by shifting conductive alloy across glass.

In an email to Tom's Hardware, Itera described the underlying approach as a form of electrowetting, where electric fields are used to precisely move liquid metal alloys across a glass substrate. Instead of relying on fixed copper traces, the system dynamically forms connections by shifting conductive liquid, effectively redrawing the...
