Silicone surface mimics topology, wettability of a real human tongue

The tongue helps people taste food, but structures on its surface also help them sense textures -- something that's also very important when savoring a meal. Now, researchers have made a 3D silicone surface that, for the first time, closely mimics the surface features of the human tongue. The material could help food scientists study mechanical interactions of foods, liquids and medicines with the organ.
