Metamaterial Textures.

We present metamaterial textures-3D printed surface geometries that can perform a controlled transition between two or more textures. Metamaterial textures are integrated into 3D printed objects and allow designing how the object interacts with the environment and the user's tactile sense. Metamaterial textures offer full control over the transformation, such as in between states and sequence of actuation. This allows for integrating multiple textures that enable functional objects such as, e.g., a transformable door handle, which integrates tactile feedback for visually impaired users, or a shoe sole that transforms from flat to treaded to adapt to weather conditions. In our hands-on demonstration, we show our 3D printed prototypes and several samples. Attendees can touch the objects and explore their different textured states.
