摘要： A method (100) of assembling an eddy current probe (50) for use in nondestructive testing of a sample is described. The method includes positioning (112) at least one substantially planar spiral drive coil (222) within the eddy current probe (50), such that the drive coil is at least one of adjacent to and at least partially within a flexible material. The method further includes coupling (114) at least one unpackaged solid-state magnetic field sensor (228) to the at least one drive coil.
