Patent Images
1. A structure for adhering to a contact surface comprising:
- a curved surface; and
a plurality of nano-fibers disposed on the curved surface, each nano-fiber having a diameter between 50 nanometers and 2.0 microns and a length between 0.5 microns and 20 microns, wherein when the curved surface is in a first position, at least one of the plurality of nano-fibers contact the contact surface and provide an adhesive force at the contact surface; and
wherein when the curved surface rotates to a second position from the first position, the at least one of the plurality of nano-fibers is leveraged way from the contact surface.

Abstract
A curved surfaces for adhering to contact surfaces is provided. The structure includes a curved surface with a plurality of nano-fibers disposed thereon. When the curved surface is in a first position, at least one of the plurality of nano-fibers contacts the contact surface and provides an adhesive force at the contact surface. When the curved surface rotates to a second position from the first position, the at least one of the plurality of nano-fibers is leveraged way from the contact surface.
