Abstract

A virtual adhesion method is provided. The virtual adhesion method includes increasing a magnetic characteristic of an initial structure, supporting the initial structure on a surface of a substrate, generating a magnetic field directed such that the initial structure is forced toward the surface of the substrate and forming an encapsulation, which is bound to exposed portions of the surface, around the initial structure.

First claim

What is claimed is:

1. A virtual adhesion method, comprising:
increasing a magnetic characteristic of an exterior outer surface of an initial structure by coating the exterior outer surface of the initial structure with magnetic particles by at least one of sputtering and electroplating;
supporting the initial structure lengthwise on a surface of a substrate;
generating a magnetic field directed such that an entire length of the initial structure is forced by magnetic attraction toward the surface of the substrate; and
forming an encapsulation, which is bound to exposed portions of the surface, around the initial structure and along the entire length thereof,
wherein the generating of the magnetic field comprises generating the magnetic field to have a magnitude insufficient to dislodge the magnetic particles coating the exterior outer surface of the initial structure from the initial structure.

2. The virtual adhesion method according to claim 1 , wherein the generating of the magnetic field comprises disposing the substrate on an electro-magnet configured to magnetically attract the initial structure and applying current to the electro-magnet.

3. The virtual adhesion method according to claim 1 , further comprising disengaging the magnetic field following partial completion of the forming of the encapsulation once walls of the encapsulation on either side of the initial structure are sufficiently tall to form a groove with opposite curved walls respectively abutting opposite curved sides of the initial structure that extends about and along the entire length of the initial structure.

4. The virtual adhesion method according to claim 1 , wherein the forming of the encapsulation comprises forming the encapsulation along the entire length of the initial structure with sufficient size to form a groove with opposite curved walls respectively abutting opposite curved sides of the initial structure that extends about and along the entire length of the initial structure to secure the initial structure to the surface.

5. The virtual adhesion method according to claim 1 , wherein the forming of the encapsulation comprises at least one of sputtering, evaporation and liquid drying.

6. The virtual adhesion method according to claim 1 , wherein the initial structure comprises a carbon nanotube, the substrate comprises an inorganic, non-metallic material and the encapsulation comprise quartz.

7. A virtual adhesion method, comprising:
coating an exterior outer surface of an initial structure with magnetic particles by at least one of sputtering and electroplating to form a magnetic particle coating on an entire length of the exterior outer surface of the initial structure;
supporting the initial structure with the magnetic particle coating lengthwise on a surface of a substrate;
generating a magnetic field directed such that the magnetic particles of the magnetic particle coating on the entire length of the exterior outer surface of the initial structure are forced by magnetic attraction toward the surface of the substrate; and
forming an encapsulation, which is bound to exposed portions of the surface, around and along the entire length of the exterior outer coating of the initial structure with the magnetic particle coating,
wherein the generating of the magnetic field comprises:
generating the magnetic field to have a magnitude sufficient to magnetically constrain the initial structure with the magnetic particle coating on the surface; and
generating the magnetic field to have a magnitude insufficient to decrease the magnetic characteristic of the initial structure by dislodging the magnetic particles coating the exterior outer surface of the initial structure from the initial structure.

10. The virtual adhesion method according to claim 7 , wherein the forming of the encapsulation comprises forming the encapsulation along the entire length of the initial structure with sufficient size to form a groove with opposite curved walls respectively abutting opposite curved sides of the initial structure that extends about and along the entire length of the initial structure to secure the initial structure to the surface.
