Abstract

Abstract: In this study, a two-axis fluxgate sensor based on PCB technology is presented. The sensor consists of multiple layers and uses silver ink to form vias. Each layer of the coil is designed in a rectangular spiral shape and a cross-shaped magnetic core is utilized to achieve two-axis sensing. The fabricated sensor consists of one excitation coil layer, three sensing coil layers and a magnetic core with dimensions of 50 mm × 50 mm. With a sinusoidal excitation signal at a frequency of 50 kHz and a current of 500 mA, the proposed sensor has a sensitivity of 2496 V T −1 at 80 µT. It can also sense vector magnetic fields in a plane by comparing the two-axis signals.
