Meiling Wang, et al., published “Measurement of Triaxial Magnetocardiography Using High Sensitivity Tunnel Magnetoresistance Sensor” on IEEE Sensors Journal.

Release time:2020-08-15
Meiling Wang, et al., published “Measurement of Triaxial Magnetocardiography Using High Sensitivity Tunnel Magnetoresistance Sensor” on IEEE Sensors Journal in July, 2019. Three-axis components of magnetocardiography (MCG) signals are measured with a high sensitivity tunnel magnetoresistance (TMR) sensor in this paper. From the measurement result, the R-wave and QRS-complex of MCG associated with the cardiac cycle are clearly observable without need of averaging. As the TMR sensor can measure MCG at room temperature, potentially it is a promising alternative to cryogenically-cooled superconducting devices to make inexpensive MCG instrumentation for extensive clinical applications.
