Abstract
A magnetoresistance sensor for use in a position and orientation tracking system includes an insulating substrate, a pattern of a metal material and/or a semiconductor material deposited on a surface of the insulating substrate, and a bias magnet material deposited over the alternating pattern of a metal material and a semiconductor material. The position and orientation tracking system includes at least one magnetoresistance reference sensor attached to a fixed object, at least one magnetoresistance sensor attached to an object being tracked, and a processor coupled to the at least one magnetoresistance reference sensor and the at least one magnetoresistance sensor.
