Abstract

Planar technology magnetometric device and manufacturing process.Applicable to obtain magnetometric sensors of the nucleus-saturated (fux-gate) type, whose purpose is to reduce the size of sensors and allow including in its related electronic structure. The sensor has a layer or substratum (1) on which along its two sides both conductor layers (2) are overlapped and that include flat spiral bobbins that, in turn, are covered by an insulating layer (3) followed by a conductor layer (4), that constitutes the connection tracks, on which an insulating layer (5) is superimposed and that is followed by a magnetic layer (6), after which the layers are repeated in reverse order, so that when equal alternating currents in opposing directions are circulated through the conductor layers (4), between which a magnetic nucleus (6) is found, said magnetic field is cancelled in the area external to the magnetic nuclei thus, conductor layers that are far away from the magnetic nucleus (6) comprise bobbins for detecting the external magnetic field.
