SML and the Herman Lab at Univ. Toronto have teamed up to introduce a novel thin-film circuit architecture that is soft, stretchable, and optically transparent. This is accomplished by patterning a thin coating of liquid metal (a eutectic alloy of gallium and indium; EGaIn) on a soft silicone film using a UV laser micromachining system. This work was recently reported in Advanced Materials and is now available online [ publisher link].
