Abstract:
1. A permanently laminated flux concentrator assembly comprising: a flux concentrator having a thickness, a top surface, and a bottom surface; and a coil embedded in said flux concentrator, wherein one side of said coil is flush with said top surface of said flux concentrator forming an exposed side and another side of said coil is embedded within said thickness of said flux concentrator forming an unexposed side, wherein said coil is capable of inductive coupling on said exposed side and is incapable of inductive coupling on said unexposed side; wherein said flux concentrator includes scoring to influence where said flux concentrator breaks in response to flexing; and a laminate adhesively and permanently secured to said flux concentrator forming a permanent bond between said laminate and said flux concentrator, wherein said laminate and said permanent bond hold together pieces of said flux concentrator that are broken at or near at least a portion of said scoring in response to flexing, wherein breaking said laminated flux concentrator does not significantly affect the magnetic properties of said laminated flux concentrator.
