A new surface that can reconfigure its shape, stickiness or slipperiness on demand, through the application of a magnetic field. The team calls its creation a Ferrofluid-containing Liquid-infused Porous Surface (FLIPS), and as the extremely forced acronym suggests, it's designed to "flip" between different states. It does so through the interactions of its two composite parts – a liquid containing magnetic particles and a solid substrate with a tiny, textured structure. [Source]
