Characterization and optimization of the device. Characterization and optimization of the device. (A) GMI ratio responses of the inductive sensing element to the magnetic field at different exciting frequencies. (B) Experimental impedance responses of the inductive sensing element to height changes. M is the remanent magnetization of the polymer magnet. Height is between the polymer magnet and the inductive sensing element. (C) The GMI ratio responses of the sensor to the displacements at different frequencies, that is, 75, 250, 750, and 1000 kHz. Displacement is the deformation of the polymer magnet under different loadings. (D) Relation of the factor of sensitivity κ of the inductive sensing element and frequency of driving current.
