▎ 摘　　要

NOVELTY - The magneto resistive sensor comprises graphene magnetic field induction array structure layer, a medium structure and graphene charge layer (5). The medium structure is located graphene the magnetic field induction array structure layer and the graphene charge layer. The graphene magnetic field induction array structure layer is graphene magnetic field induction circular array structure layer or graphene magnetic field induction rectangular array structure layer. USE - Magneto resistive sensor based on magnetic field induction graphene structure used for power industry field power operation device, such as current measurement, fault position measurement, movement speed of power device action, angle and angular velocity measurement. ADVANTAGE - The magneto-resistive sensor has high anti-interference ability and high precision, it greatly improves the sensitivity of the magneto resistive sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a side sectional view of a magneto resistive sensor. 1Magnetic field sensing area 2Insulating layer 3Conductive strip 4Dielectric layer 5Graphene charge layer
