MAGNETORESISTIVE SENSORS

It is a new trend in sensors utilizing the principle of the magnetoresistance – dependence of electrical resistance of some materials on the magnetic field strength.

When using magnetoresistive chip, a change in the magnetic field results in a change in the resistance on the chip output.

They are used for sensing the position, speed, and for contactless measurement of current.

At present, co-operation on their development is ongoing between the Faculty of Electrical Engineering of Czech Technical University in Prague and the chip manufacturers themselves.
