Abstract

A wireless magnetic motion capture system is one such effective technique for body motion analysis in the field of medical treatment. The applications require a small and thin marker that can be attached to anywhere of a body without breakage. Therefore, thinned LC marker composed of a laminated amorphous ribbon core and a 0.5 mm-thick ferrite plate core were prepared and evaluated. Although, in addition, the ribbons were subjected to field-annealing to control its magnetic anisotropy, there were no differences as the capability of the LC marker. The results reveal that, only near the pick-up coil array (up to 70 mm), the system is capable of detecting the position of the thinned LC marker with the accuracy to around 1 mm.
