Abstract

This paper proposes a simple charge balancing method for voltage mode stimulation which can precisely balance the injected charge in order to avoid electrode dissolution or tissue damage using high-frequency voltage pulses. By explaining the tissue model, the effect of such a high-frequency pulses is investigated. Additionally, a prototype of the system is implemented by employing low power off-the-shelf discrete components. The experimental results show the proper performance of the proposed system.
