Multi-turn counter sensor

A multi-turn counter (MTC) sensor comprising:

• a magnetic strip comprising:
• a domain wall generator located at a first end of the magnetic strip,
• the domain wall generator to generate at least one domain wall in the magnetic strip, the at least one domain wall configured to propagate based on a magnetic field caused by a magnet,
• wherein a location of the at least one domain wall indicates a turn count of the magnetic field of the magnet;
• the turn count to indicate one or more of a predefined fraction of a full rotation of the magnetic field;
• an end tip located at a second end of the magnetic strip,
• the second end of the magnetic strip being opposite the first end;
• and
• a plurality of phase delaying bends to cause a delay of propagation of the at least one domain wall with regard to an orientation of the external magnetic field based on a rotation of the external magnetic field.

A multi-turn counter (MTC) sensor comprising:

• a magnetic strip comprising:
• a domain wall generator located at a first end of the magnetic strip;
• an end tip located at a second end of the magnetic strip,
• the second end of the magnetic strip being opposite the first end, and
• a plurality of strip turns between the domain wall generator and the end tip;
• and
• an integrated magnetic concentrator (IMC) layer configured between at least a part of the magnetic strip and a magnet that causes a magnetic field,
• wherein the IMC is to reduce a strength of the magnetic field to enable the MTC sensor to count a number of rotations of the magnet based on detecting movement of domain walls in the magnetic strip caused by the magnetic field.
