Eddy currents are an electromagnetic phenomenon that represent an inexhaustible source
of inspiration for technological innovations in the 21st century. Throughout history, these …

Giant magnetoresistance (GMR) sensors have been used in non-destructive testing based
on eddy current (NDT-EC). The low-pass filtered GMR-based NDT-EC have been …

Magnetic induction tomography (MIT) is largely focused on applications in biomedical and
industrial process engineering. MIT has a great potential for imaging metallic samples; …

The detection of defects in aluminium alloys using eddy current testing (ECT) can be
restricted by higher electrical conductivity. Considering the occurrence of discontinuities …

Low-field nondestructive evaluation techniques have witnessed considerable improvements
with the development of highly sensitive magnetic field sensors. Low-field techniques have …

In this thesis the development and application of compact low cost MIT instruments are
investigated, specifically for the purpose of integration into systems for in situ monitoring of …
