Abstract

The aim of this study is to investigate the use of a new pulse shape to obtain anodal blocking. This new pulse shape requires less charge per pulse compared to the conventional rectangular pulse and would therefore be safer in a chronic application. Computer simulation, used in this study show that using modified pulse shapes, charge reduction up 30.4% to can be achieved.
