Neurostimulation development is significant for neuroscience research and neurological disease therapy. Compared to conventional electrical neurostimulation methods, magnetic neurostimulation offers better performance in terms of orientational selectivity. This paper presents a feasibility of intracortical micro-coil design for high-resolution magnetic neurostimulation to improve their selectivity. We have proposed and simulated two different micro-coil designs (‘half-V-shape’ coil, and double-loop rectangular coil) using finite element method in COMSOL Multiphysics. The simulations results show that ‘half-V-shape’ coil has a selectivity ratio of 1.10 and 1.29 for double-loop rectangular coil. Since it is still unclear of how to create selectivity in magnetic neurostimulation methods, our modellings will provide guidance to future selective micro-magnetic neurostimulation coil design and fabrication.
