Abstract: A novel neural electrode based on small-deflection theory to reduce the tissue injury caused by micromotion was designed to improve the lifetime of neural electrode. The results of the finite element analysis revealed that the novel neural electrode showed excellent micromotion-attenuation capability. And designing a reasonable size of opening area can effectively improve neural electrode-brain tissue interface mechanical states. The novel electrode is inferred to prolong the lifetime of neural electrodes.

Keywords: Neural electrode, small-deflection theory, finite element method (FEM), micromotion
