Abstract
An apparatus for detecting a change of a physical quantity by means of a conductor structure having a processor for applying a defined supply signal to the conductor structure so as to effect a current flow through the conductor structure, the current flow being changeable by the physical quantity, and a detector for detecting a magnetic field caused by the current flow through the conductor structure by means of a magnetoresistive element allocated to the conductor structure, a change of the physical quantity being associated with a change of the detected magnetic field.
