Researchers have demonstrated the ability to switch the surface of liquid metal between reflective and scattering states. The technology could one day be used to create electrically controllable mirrors or illumination devices.
Mirrors and other reflective optical components are typically created through the use of optical coatings or polishing processes. The researchers’ approach, developed by a team led by Yuji Oki of Kysuhu University in collaboration with a team from North Carolina State University led by Michael Dickey, used an electrically driven reversible chemical reaction to create a reflective surface on the liquid metal. Switching between the reflective and scattering states can be done with just 1.4 V, about the…READ MORE
