Dipolar-biased giant magnetoimpedance
Abstract The effect of the dipolar field on the magnetoimpedance in Fe- and Co-based wires is presented. In the experiments a Co-based wire was used as a probe to measure the giant magnetoimpedance (GMI), while a Fe-based wire was employed to generate the dipolar field.

Wearable Magnetic Field Sensor with Low Detection Limit and Wide Operation Range for Electronic Skin Applications. [PDF]
A flexible magnetic sensor with low detection limit and wide measuring range is reported, realized by the anisotropy of the giant magneto‐impedance effect of amorphous wire. The sensor can detect the magnetic field from 22 nT to 400 mT, and simultaneously monitor weak magnetic fields such as geomagnetism and large magnetic fields which come from ...
