Conducted Disturbance Robustness Evaluation of a Magnetic Short-Range Localization System

In this article, a metrological characterization of the performance of a wireless localization system is carried out, considering the typical disturbances affecting the medical environment. Such system will be used in specific biomedical applications, including a glove for accurate tracking of unconstrained movements. To this purpose, the authors participate to a national project “Six DOF scalable finger tracking system”, whose goal is to develop a short-range wireless localization system with six degrees of freedom. The realized system will guarantee the real-time tracking of the fingers of the hand to provide support for the rehabilitation of patients with reduced motor skills. Obtained results, which exhibit a worsening in localization error due to disturbance effects, paths the way to a more robust transmission method able to reject or minimize single ton disturbance effect.
