Material may also relate to systems and methods described in U.S. Provisional Patent Application 61/796,253, filed Nov. 5, 2012, titled “System for Controlling Magnetic Flux of a Multi-pole Magnetic Structure”, which is incorporated herein by reference.

In some applications, it is desired that magnetic structures be constructed in such a way that they are capable of being flexibly deformed. For example, any situation involving a need for a magnetic structure to be wrapped around or within another object is often better served by a flexible or semi-flexible magnetic structure than by an entirely rigid magnetic structure. There exist flexible materials that are entirely magnetizable, however there are limits to the magnetic field strength that can be imparted to magnetic structures constructed of these materials. There also exist flexible materials in which solid magnetizable particles are embedded. However, these materials also suffer many of the same drawbacks, as the low ratio of magnetizable to nonmagnetizable material imposes a limit on the magnetic field strength that can be provided. One possible solution to these problems is to attach rigid magnetizable elements to a layer of flexible material in order to provide a desired magnetic field strength while still allowing at least some flexibility, where each rigid magnetizable element is a solid piece of magnetizable material instead of a non-magnetizable material in which solid magnetizable particles are embedded. As such, each piece of solid magnetizable material is fully magnetizable. An example of a solid magnetizable material that can be used in accordance with the invention is a piece of neodymium iron boron (NIB) magnetizable material.
C 100. Semi-flexible magnetic structure 100 can include a flexible layer 102. Flexible layer 102 can be constructed of any desired flexible material, for example, rubber, plastic, fabric, or any other flexible material as desired. In addition to being flexibly deformable, flexible layer 102 can also be elastically deformable.
Semi-flexible magnetic structure 100 can also include an array of magnetizable elements 104, which can be adhered, attached, or otherwise disposed on flexible layer 102. Magnetizable elements 104 can be constructed of any desired magnetizable material. Magnetizable elements 104 can be any shape or size as desired, and can be arranged on flexible layer 100 in any desired pattern or configuration. Once magnetizable elements 104 are added to layer 102, they can be magnetized as discussed in U.S. Pat. No. 8,179,219 filed 2 Jun. 2009, titled “Field Emission System and Method,” which is hereby incorporated herein. For simplicity, the drawings provided herein depict only one magnetic source per magnetizable element but as described in U.S. Pat. No. 8,179,219, a piece of magnetizable material (or magnetizable element) can have multiple magnetic sources magnetized at different locations on the magnetizable material in any desired polarity pattern including adjacent magnetic sources that have the same polarity or opposite polarity. Generally, one skilled in the art of magnetizing will recognize that a semi-flexible magnetic structure can be magnetized as if it were one piece of magnetizable material, where a given magnetizing field may magnetize a magnetic source into only one magnetizable element or may magnetize across two or more magnetizable elements depending on the size of the aperture of the magnetizer's inductor coil, the size of the magnetizable elements, and the magnetizing field strength.
In this way, semi-flexible magnetic structure 100 can be a grid of solid magnetic material which can be magnetized in any desired pattern and which can be supported by a flexible material in such a way that semi-flexible magnetic structure 100 is at least partially flexibly deformable.
The bend modulus or diameter around which semi-flexible magnetic structure 100 can be bent can be affected by the size, shape, and spacing of magnetizable elements 104. Increasing the spacing between magnetizable elements 104 or decreasing the size of magnetizable elements 104 can decrease the diameter which semi-flexible magnetic structure 100 is capable of accommodating.
In some embodiments, semi-flexible magnetic structure 100, flexible layer 102, and magnetizable elements 104 can be any size, shape or configuration as desired. As an example,
The exemplary semi-flexible magnetic structures thus shown have been made up of rows and columns of magnetizable elements. However, semi-flexible magnetic structures can be produced of magnetizable elements having other orientations where the spacing between elements can be uniform or non-uniform or any desired combination to include random. As yet another example,
In other embodiments, semi-flexible magnetic structure 100, flexible layer 102, and magnetizable elements 104 can be configured in any other shape or size as desired, where elements 104 can have the same shape but vary in size, have the same size but vary in shape, or any other desired combination. One skilled in the art will recognize that a given semi-flexible magnetic structure can have different portions that are designed such that one portion has a different bend modulus from another portion and that different portions can be magnetized to have different magnetic properties including field strengths, different tensile forces, different shear forces, and the like. Moreover, coded polarity patterns can be implemented so that semi-flexible magnetic structures can correlate with each other, etc. Generally, coded polarity patterns that can be applied to rigid magnetic materials can be applied to semi-flexible magnetic structures as taught herein and also to prior art flexible materials.
While particular embodiments of the invention have been described, it will be understood, however, that the invention is not limited thereto, since modifications may be made by those skilled in the art, particularly in light of the foregoing teachings.
