“…In recent years, the magnetoresistive sensors based on anisotropic magnetoresistive (AMR) have attracted great attention owing to their high sensitivity at weak magnetic fields, the flexibility of the design, and compatibility with standard microelectronics technology [1][2][3][4][5]. The magnetoresistive sensors are commonly used for magnetic bead detection [6], biosensors and biochips [7,8], applications to microcompass [9], and flexible magnetic sensors [10,11].…”
