Electrodeposited multilayered nanowires, grown in a polycarbonate membrane, represent a new medium in which perpendicular to the plane giant magnetoresistance (GMR) has been observed. These nanostructures can reach a GMR change of up to 22% at ambient temperature. In this paper we present the application of the multilayered nanowires and a preliminary characterization of a angular position sensor. The sensitive elements are mounted in a special arrangement (two 45 degrees phase shifted Wheatstone bridges) and provide a pair of sine-cos waveforms as outputs.
