摘要：

We have developed a cheap and simple trilayer printed circuit board (PCB)-based technology, adapted for the fabrication of fluxgate magnetic sensors. The two outer layers of the PCB stack comprise the electrical windings of the fluxgate, while the inner layer is made of patterned amorphous magnetic core with extremely high relative magnetic permeability (mu(r) approximate to 100,000). The output voltage and the sensitivity of the fluxgate devices have been studied as a function of the external field and of the geometry of the magnetic core;. We have found a relatively high sensitivity of Is V/T at an excitation current frequency of 10 Wiz, The results obtained clearly show the potential of this miniaturised fluxgate device for application as a magnetic field sensor.
