Abstract

Aus Schichtsystemen mit wenigstens einer Polymerschicht gebildete Magnetsensoren sind bekannt. Bei einem solchen Schichtsystem ändert sich der elektrische Widerstand in Abhängigkeit vom Magnetfeld. Dabei sind im Allgemeinen nicht lineare Kennlinien vorhanden, die glockenförmig verlaufen können. Gemäß der Erfindung ist auf oder unter der wenigstens einen Polymerschicht ein zusätzliches magnetisches Schichtsystem angeordnet, das aufgrund seines Streufeldes eine magnetische Vorspannung der Kennlinie des Polymer-Magnetsensors bewirkt. Mit einer Anordnung aus mehreren derartigen Magnetsensoren kann eine Brückenschaltung zum Einsatz für eine praktische Messung gebildet werden.
