Liquid Metal Printer Lays Electronic Circuits on Paper, Plastic and Even Cotton
The new technique is straightforward. The magic sauce is a liquid metal: an alloy of gallium and indium which is liquid at room temperature. They simply pump it through an inkjet printer to create a fine spray of liquid metal droplets that settle onto the substrate.
Perhaps most exciting of all is that the technology behind all this is cheap and simple: there’s no reason why it couldn’t be pushed to market very rapidly. And that raises the prospect of being able to print prototype circuits in small businesses and even at home.
Das darf getrost als technischer Durchbruch gefeiert werden, auch wenn die Lösung simple und naheliegend klingt.
