3D model simulation on magnetic induction spectroscopy for fetal acidosis detection using COMSOL multiphysics

Conventional fetal scalp blood sampling required an invasive measurement to detect fetal hypoxia in fetus. This paper describes non-invasive technique employing single channel magnetic induction technique as a solution to replace conventional technique nowadays. The objective of the simulation is to evaluate the magnetic induction spectroscopy setup for acidosis detection and to determine the most suitable types of coil to be used for better result in detecting acidosis in fetal blood. Result shows that primary field can be penetrates to the desired material and there are difference in pattern for both linear coil and circular coil. The result of the simulation is important and need to be considering in order developing the magnetic induction spectroscopy hardware to increase the accuracy of the system.
