Figure 2. Design of Hall sensors and magnetic films. (A) Structure of flexible Hall sensors; (B) Output response of Hall sensors; (C) Sensitivity comparison of nine Hall sensors; (D) Noise testing of Hall sensors; (E-G) Simulation results of the x, y, z-axis magnetic field of the perpendicularly periodic magnetized film; (H) Test results of the z-axis magnetic field of a vertically periodic magnetized film; (I) SEM image of the magnetic film. SEM: Scanning electron microscope; PET: polyethylene terephthalate.
