Wearable Magnetic Field Sensor with Low Detection Limit and Wide Operation Range for Electronic Skin Applications. [PDF]
Adv Sci (Weinh)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 ...

Giant magnetoimpedance sensors [PDF]
IEEE Instrumentation & Measurement Magazine, 2001 Magnetoinductance and giant magnetoimpedance (GMI) sensors have greatly benefited from the development of amorphous wires. These soft ferromagnetic substances exhibit exquisite sensitivity (in the nT range) and wide bandwidth (MHz) in thin film structures. Combining these properties with surface wave technology produces passive, wireless sensors.

Perspectives in Giant Magnetoimpedance Magnetometry [PDF]
Sensor Letters, 2009 Approximate expressions are obtained for the sensitivity of a GMI wire. The optimal conditions for high sensitivity are discussed in terms of material and external parameters, such as dc field, dc current bias, driving current amplitude and frequency. We show that the systematic reduction of the anisotropy field is not necessarily the best approach to ...
