- Abstract
- In this paper, we propose a new array-type transcranial direct current stimulation (tDCS) system, which can modulate cortical excitability of human brain in a more effective manner. Once a target location inside a brain is determined, optimal injection current/potential at each electrode is calculated automatically by solving a constrained optimization problem. Current density distribution in a realistic head model was evaluated using the 3-D finite element method (FEM) adopting the superposition principle. Simulation results demonstrated that the proposed tDCS system enables effective and accurate field concentration on targeted brain areas.
