Researchers from the Functional Materials Laboratory at the Swiss Federal Institute of Technology in Zurich have developed a silicone heart that beats almost like a human heart.

The artificial heart really looks like a real heart. And this is the goal of the first entirely soft artificial heart: to mimic its natural model as closely as possible.

The soft artificial heart was created from silicone using a 3D-printing, lost-wax casting technique; it weighs 390 grams and has a volume of 679 cm3.
