Abstract:
In this paper, we present a high performance Giant Magneto-Impedance (GMI) sensor for biomagnetic field measurement. We used a first order gradiometer based on amorphous wire GMI sensor for measuring cardiac magnetic field and brain magnetic field. The measured results of a cardiac magnetic field perpendicular to the breast plane (cardio apex position) and simultaneously recorded Electrocardiography (ECG) are shown. The spontaneous brain activity (Alpha rhythm) measurements were carried out on a female subject by GMI sensor and simultaneously recorded Electroencephalography (EEG).
