Meiling Wang, Xinchen Tao et al., published “Imaging of Magnetic Nanoparticles Using Small TMR Sensor with An Excitation-Compensation Scheme” on IEEE Sensors Journal

Release time:2020-08-15

Meiling Wang, Xinchen Tao and Chaofeng Ye published “Imaging of Magnetic Nanoparticles Using Small TMR Sensor with An Excitation-Compensation Scheme” on IEEE Sensors Journal in May, 2020. This paper studied the feasibility of using a small TMR sensor with an excitation compensation scheme for MPI. It was shown that the sensor has a wide measurement range from -100 to 100 Gs. The sensitivity of the sensor is about 12 μV/V/Gs. For further proof of the system's capabilities, we prepared an ‘L’- shaped sample formed by 6 holes to image after all the above quantitative exploration and analysis.
