Abstract: Sensors based on the AMR effect can be manufactured lithography-free using pre-structured PEEK substrates for the MR strips. If a magnetic field is applied in parallel to the AMR strips (the non-sensitive axis), a change in resistance is still produced, since the current direction in the meander arcs is locally perpendicular to the magnetic field. But in combination with non-MR materials made by laser direct structuring for connections instead of classical meander arcs eliminates the undesired resistance change in the non-sensitive axis and improves the angle dependent measurement.
