SNAPPING SURFACES FOR SENSORS AND ADHESION CONTROL
This invention involves creating shape transition at responsive interfaces or surfaces by employing simple features such as shells, plates or columns, that are integrated into a material's surface or interface through simple processes of molding or self-assembly.  Upon application of a given stimulus (e.g. weight, light, chemical, thermal) the structures will spontaneously transform their shape due to the onset of elastic instability.  This instability is a "snap-through" event which induces the shape transition of the material surface.
