Technical Aspects of Electrical Neurostimulation

Abstract

This paper deals with technical aspects of electrical neurostimulation. Attention is given to problems of transmission of signals and power through inductive link created by coupled resonant circuits. Both geometric and electronic approaches are shown and compared. In geometric approach factors influencing mutual coupling are presented. In electronic approach two types of tuning of coupled resonant circuits are presented. The main stress is laid upon the principle of stagger tuning. At the end an example of stimulator using coupled resonant circuits stagger tuned is given.
