Abstract
A fabricated microstructure includes a base and one or more nano-structures disposed on one or more portions of the base to adhere to a contact surface. The one or more portions of the base with the one or more nano-structures are located on the base such that, when the one or more nano-structures adhere to the contact surface and an external force is applied to peel the base from the contact surface, the one or more nano-structures in the one or more portions of the base facilitate or resist peeling of the nano-structures from the contact surface.
Claims22
A fabricated microstructure, comprising:
- a base;
- and
- one or more nano-structures disposed on one or more portions of the base to adhere to a contact surface,
- wherein the one or more portions having the one or more nano-structures are located on the base such that, when the one or more nano-structures adhere to the contact surface and an external force is applied to peel the base from the contact surface, the one or more nano-structures in the one or more portions of the base facilitate or resist peeling of the nano-structures from the contact surface.
A method of forming a fabricated microstructure to adhere to a contact surface, comprising:
- forming a base;
- and
- forming a plurality of nano-structures disposed on one or more portions of the base to adhere to the contact surface,
- wherein the one or more portions having the one or more nano-structures are located on the base such that, when the one or more nano-structures adhere to the contact surface and an external force is applied to peel the base from the contact surface, the one or more nano-structures in the one or more portions of the base facilitate or resist peeling of the nano-structures from the contact surface.
A method of adhering a fabricated microstructure to a contact surface, comprising:
- obtaining a base having one or more nano-structures disposed on one or more portions of the base;
- and
- placing the base having the one or more nano-structures on the contact surface,
- wherein the one or more portions having the one or more nano-structures are located on the base such that, when the one or more nano-structures adhere to the contact surface and an external force is applied to peel the base from the contact surface, the one or more nano-structures in the one or more portions of the base facilitate or resist peeling of the nano-structures from the contact surface.
A fabricated microstructure, comprising:
- a substrate;
- and
- at least two seta structures configured to adhere to a contact surface by van der Waals forces, wherein the at least two seta structures are disposed on the substrate in opposing orientation to resist peeling when the at least two seta structures adhere to a contact surface.
