Platinum, copper, nickel alloy may be key for smart biomedical devices

Researchers at the Ecole Polytechnique Federale de Lausanne in Switzerland have used an amorphous metal alloy composed of platinum, copper, nickel and phosphorous to make electrodes for plastic fibres.

The idea behind their work is that these electrodes are incorporated into biomedical devices such as chronic implants and electronics.

“Our metallic glass is part of a new category of metals with an amorphous structure,” Inès Richard, one of the scientists involved in the project, said in a media statement. “When the alloy is heated to a certain temperature, it first turns viscous and then becomes crystalline and solid.”
