A short review of magneto-impedance effect for biosensor

This short review paper is organized the following: a material with high magnetoimpedance effect, a various of the patterned in magneto-impedance sensor and bio-magneto impedance application. Various of the magnetic material is presented such as a wire magnetic, ribbon, a magnetic thin films as well as multilayers structure. A pattern of the magneto impedance sensor is also presented in this paper. Finally, recently progress of the bio-magneto-impedance sensing biomagnetic fields of human are reviewed. (paper)
