Researchers at the Technical University of Hamburg and the Helmholtz Center Geesthacht have engineered a new nanomaterial that changes from hard to soft with the flip of a switch.
The material is essentially an electrically tunable metal that can be hard and brittle or soft and malleable depending on the charge passing through it. To create the material, researchers placed precious metals like gold and platinum in an acidic bath, where corrosion cuts tiny porous channels or ducts through the metal. Those interior channels are then filled with a conductive liquid partner, like a diluted acid or saline solution.
I wonder if it would make a good heatsink, with all the shape shifting and what not.
