Abstract
In order to provide a contactless measurement technique for the detection of surface damages, a modular design of an eddy current micro sensor was developed and fabricated in thin-film technology. The sensor is intended to be applied for the detection of cracks in ferrous and nonferrous metals. The sensor consists of two parts, a single-turn excitation coil and an anisotropic magneto-resistance (AMR) sensor. The AMR sensor detects the change of the magnetic field induced in the sample by the excitation coil. The sensor is capable of detecting defects which are smaller than 50 μm.
