High sensitive magnetic GMI-based sensing elements array for biosensor protoptype

Magneto-impedance (MI) response in single glass-coated amorphous microwire and, respectively glass-coated amorphous microwires array in the presence of Fe-based magnetic liquid was studied. Major differences of the magneto-impedance response are obtained when microwires array is used. Magneto-impedance was strongly influenced by magnetic liquid covering only about 8% of array.
