Tunnel magnetoresistance(TMR)sensor arrays represent an effective method for current measurement

but inaccurate offset angles of the arrays lead to severe crosstalk interference.A V-shaped magnetic sensor array with effective crosstalk interference suppression capability is proposed.A mathematical model of magnetic field interference degree(MFID)is established to calcuate the optimal offset angle(OOA).Finite element simulation and experimental analysis are utilized to verify that the V-shaped magnetic sensor array with the optimal offset angle can effectively suppress crosstalk errors.Two groups of experimental results demonstrate that the maximum crosstalk errors of the V-shaped array with the optimal offset angle are 2.17% and 1.68%

respectively

which are lower than those of V-shaped arrays with other offset angles and two traditional arrays.The experimental results verify the effectiveness of the proposed method.
