Method for calibrating sensitivity tensor of triaxial magnetoelectric coupling sensor

The invention provides a method for calibrating the sensitivity tensor of a triaxial magnetoelectric coupling sensor, which comprises the following steps of: defining the direction of the triaxial magnetoelectric coupling sensor to be tested, putting the triaxial magnetoelectric coupling sensor to be tested on a high-precision triaxial rotating table, putting the triaxial magnetoelectric coupling sensor and the high-precision triaxial rotating table in a single-axis Helmholtz coil together, and calibrating the sensitivity tensor of the triaxial magnetoelectric coupling sensor to be tested. An alternating magnetic field is applied to the three-axis magnetoelectric coupling sensor through the single-axis Helmholtz coil; the three-axis magnetoelectric coupling sensor is controlled through a high-precision three-axis rotary table to enable the X-axis direction, the Y-axis direction and the Z-axis direction of the three-axis magnetoelectric coupling sensor to be parallel to the axis direction of the single-axis He
