MIT has some of the finest researchers around. Their latest creation is quite special. It is a flexible material that is inspired by animal hair. It moves in responsive to a magnetic field. Their orientation can be controlled using an external magnetic field. The surface consists of a thin, flexible polymer skin and a ferromagnetic hair like micropillar array.

Magnetic Hair
The pillars can control the direction in which fluids spread through the material. The material can direct water upward against gravity. The material’s tilting pillars can also affect optical patterns. Think about the possibilities here. This material can be used for fluid or light manipulation in artificial skin, cell manipulation, and smart windows.
