ABSTRACT
Introduction of magnetic elements into electronic devices made of polymer composites appears as a new technique in the eld of electrical engineering and biomedical research for sensor applications.
The correlation between the magnetic properties of soft magnetic materials and their elastic or electrical response causes different phenomena that can be used for the construction of magneto-impedance sensors (namely the skin-effect-induced change of impedance caused by an applied magnetic eld)—especially for geomagnetic and biosensing applications, magnetoelastic resonance sensors (occurring when a mechanical resonant response is excited through the magnetostrictive effect of soft magnetic materials)—when applied as remote sensors and as magneto-electric laminated composite sensors (obtained from combining magnetostrictive amorphous ferromagnetic ribbons with piezoelectric materials), show an extremely high sensitivity for magnetic eld detection (García-Arribas et al. 2014; Prinz 1999).
