Abstract

Nano-machines circulating inside of a human body and gathering data about tissue conditions are a part of next generation medical diagnostic systems. However, in order to perform their functions properly, these devices should report not only their medical measurements, but also their positions. In this paper, a new localization approach for in-body nano-machines based on magnetic field is presented, taking advantage of a very good magnetic permeability for all human tissues. The whole proposed localization system is described, starting from 10×10 μm2 magnetometers to be integrated into the nano-machines, to a set of external wires generating the magnetic field. Mathematical equations for localization algorithm are also provided, assuming the nano-machines do not perform the calculations themselves, but they transmit their magnetic field measurements together with medical data outside of the body. The whole system is validated with computer simulations taking into account the measurement error of the magnetometers, the error induced by the Earth’s magnetic field and a human body model assuming different possible positions of nano-machines. The results show a very good system accuracy with localization error even below 1 cm.
