Abstract:
A method for fabricating a micro-machined electromechanical device comprising the steps of:depositing a first plurality of stripes of a ferromagnetic material onto a first sensor structure, wherein each of the first plurality of stripes is oriented approximately along a first axis;depositing a second plurality of stripes of a ferromagnetic material onto a second sensor structure, wherein each of the second plurality of stripes is oriented approximately along a second axis, approximately perpendicular to the first axis; andapplying a magnetic field to the device, wherein the magnetic field is oriented along a first direction within a plane formed by the first axis and the second axis, the first direction being at an angle approximately 45 degrees from the first axis, and wherein application of the magnetic field causes a magnetic dipole to be formed in the first plurality of stripes along the first axis and causes a magnetic dipole to be formed in the second plurality of stripes along the second axis.
