Elastocaloric cooling – world’s first refrigerator cools by flexing artificial muscles made of nitinol, a nickel-titanium alloy. This climate-friendly cooling and heating technology is far more energy-efficient than current methods.

There is room for just one small bottle in the world’s first refrigerator that is cooled with artificial muscles made of nitinol, a nickel-titanium alloy. But the mini-prototype that the team led by professors Stefan Seelecke and Paul Motzki will be presenting at the Hannover Messe is groundbreaking: it shows that elastocalorics is becoming a viable solution for practical applications. This climate-friendly cooling and heating technology is far more energy-efficient than current methods.
