Abstract

A magnetic field transducer based on the giant magnetoimpedance (GMI) effect has been developed by the Laboratory of Biometrology at PUC-Rio. It is aimed at biomedical applications, especially three-dimensional localization of needles accidentally inserted in the human body. This manuscript presents some new measurements that led to a better understanding of the prototype’s behavior.
