Abstract
In order to ensure long electrode lifetime, charge balance is necessary for electrostimulation. If charge balance is obeyed, the reversible reactions are used to prevent the electrode state to change over time. In the literature, it is usually assumed that when biphasic, charge-balanced current pulses are used, ideal charge balance is achieved. Figure 3.1 shows three common types of biphasic charge balanced current pulses mentioned in the literature. The monophasic capacitor-coupled waveform is generated through a capacitor discharge circuit [1].
