Giant magnetoresistance (GMR) sensor has been developed and widely applied to use as magnetic read head in data storage industry. This paper describes new applications of magnetic-field measurement with high spatial-resolution and high sensitivity to nondestructive evaluation and biomedical engineering. For nondestructive evaluation, the GMR sensor, used as magnetic sensor based on eddy-current...

This paper presents a nondestructive, high frequency electromagnetic evaluation method which can be applied for the examination of periodic conductive strips or conductive fibers using the evanescent modes generated in slits or in dielectric insulation between conductive fibers. For the detection of evanescent waves we propose the use of lenses with metamaterials, both conical Swiss roll type a...

currently, nondestructive quality evaluation of various agricultural products are being developed and used. in this study, application of an electronic nose system for the quality assessment of kiwifruit (abbot variety) is used. electronic nose system coupled with artificial neural network (ann) and principal component analysis (pca) techniques was able to classify unripe, half-ripe, ripe, over...

The purpose of this study was to investigate the application of nondestructive testing in cyclic fatigue evaluation of endodontic ProFile nickel-titanium (NiTi) rotary instruments. As-received ProFile instruments were made to rotate freely in sloped metal blocks by a contra-angle handpiece mounted on a testing machine. Rotation was interrupted periodically, and the instrument removed and engage...
