This article reviews the physical mechanism of spin-dependent magnetoresistance and its early application in sensors. The magnetic field performance generated by the current to be measured is explained. According to the realization of the magnetoresistance measurement of this characteristic, seven main indicators of the current sensor are summarized. Starting with the structure of magnetoresistance devices and magnetoresistance units of current sensors based on spin-dependent magnetoresistance effect, several design methods of sensors and their advantages and disadvantages are analyzed. Starting from the role of AMR, GMR and TMR in magnetoresistance cells, the structure of series and parallel arrays, permanent magnet bias, coil bias, coil reset, flux aggregator and superconducting ring are analyzed, and several design methods of sensors are summarized as well as their advantages and disadvantages. Finally, the possible development direction of the current sensor is forecasted based on the recently discovered spin correlation effect.

We present the design of a magnetic encoder to measure angular position. The proposed encoder includes two Hall sensors in quadrature in a fixed platform. In addition, and over the sensors, there are two permanent magnets in a shaft. The relative motion between the fixed and the movable components generate a voltage variation in the sensors, which serve to generate the approximation of the angular position. We detail the acquisition process and the linearization method, because we consider that these are the most important contributions of this work. Lastly, we show the application of the encoder in the position control of a direct current motor to show the performance of the encoder estimating fast and slow angular position changes.
