Patent ID: 8742520

Claim:
A device for sensing magnetic fields, the device comprising: a substrate member having a surface region; an integrated circuit (IC) layer spatially disposed overlying at least a portion of the surface region; a first magnetic field sensor element including at least a first material and configured to detect at least in a first direction, the first magnetic field sensor element being operably coupled to the IC layer; a second magnetic field sensor element including at least the first material and configured to detect at least in a second direction, the second magnetic field sensing element being operably coupled to the IC layer; a third magnetic field sensor element including at least the first material and configured to detect at least in a third direction, the third magnetic sensing element being operably coupled to the IC layer; and at least one magnetic field concentrator spatially formed overlying at least one portion of the surface region; wherein all of the first, second and third directions are configured in a mutually orthogonal manner.
