Neural disorders like epilepsy, Parkinson’s disease and Alzheimer’s disease have become a major area of concern because of their complexity and the huge number of occurrences. At present, most of the treatments are based on drugs and external nerve stimulation demanding critical care.

This study aims at the design and simulation of an implantable micro-electrode which can lead to better understanding of the brain. This electrode can be used for the electrical stimulation of the brain and can essentially aid in the diagnosis and treatment of patients with neural disorders.

The electrode design consists of shanks which are arranged in a uniform pattern to facilitate accurate delivery of required current to the affected sites. The micro-electrode was modeled and simulated using the MEMS module of COMSOL Multiphysics 4.1.
