Characterization of Metglas/poly(vinylidene fluoride)/Metglas magnetoelectric laminates for AC/DC magnetic sensor applications

Polymer-based magnetoelectric materials show increasing interest for a large number of applications and, in particular, for the development of magnetic sensors. Nevertheless, relevant parameters such as sensitivity, accuracy, linearity, hysteresis and resolution have been vaguely or never discussed....

Descrição
Resumo:Polymer-based magnetoelectric materials show increasing interest for a large number of applications and, in particular, for the development of magnetic sensors. Nevertheless, relevant parameters such as sensitivity, accuracy, linearity, hysteresis and resolution have been vaguely or never discussed. This work reports on those parameters on a Metglas/Poly(vinylidene fluoride)/Metglas magnetoelectric laminate. The sensitivity and resolution determined for the DC (30 mV.Oe -1 and 8 µOe) and AC magnetic field sensor (992 mV.Oe -1 and 0.3 µOe) are favorably comparable with the most sensitive polymer-based ME sensors. Further, the correlation coefficient, linearity and accuracy values are 0.995, 95.9% and 99.4% for the DC magnetic field sensor and 0.9998, 99.4% and 99.2% for the AC magnetic field sensor. Therefore, the magnetoelectric materials reported in the present study can be used for innovative AC/DC magnetic field sensors.
