Detection device for detecting local magnetic fields

The invention relates to a detection device for detecting local magnetic fields. The detection device according to the invention is characterized in that it consists of an array of capacitive sensors 1, preferably a sensor array, wherein the sensors 1 are covered with a foil. The film consists of either the composite of a piezoelectric layer 2 and a ferromagnetic layer 3 or from chiral material (Fig. 2).
