Abstract

High sensitivity, quick response, small size, non-contact sense and low-power requirement, make amorphous wires attractive for sensors and micro-sensors realization. Negative factors accompany magneto-impedance sensors based on amorphous wires. They must be compensated for an efficient use of the devices and therefore the behavior of the sensing element must be well characterized. The paper highlights most important characteristics of amorphous wires and proposes an instrumentation set-up based on vector-voltmeter analyzer useful for carrying out their measurement.
