Abstract:
Combining the material science and microelectronics, using the technology of signal modulation and demodulation, a new kind of high sensitivity magnetic sensor based on the effect of giant magneto-impedance was designed. The sensor features a small size of 28mm×15mm×4mm, high sensitivityof 6.SmV/μT, and non-linearity of less than 0.78% ES. At last, the characteristic of amorphous wire, circuit design of sensor and data analysis of experiment were presented.[著者文摘]
