An experimental study on passive charge balancing

[摘要] This paper presents a simplified analysis of the electrode potential uponmismatched, biphasic stimulation using passive discharge techniques, e.g. byshortening of the electrodes. It turns out that especially formicroelectrodes the required shorting intervals become as large as to limit afeasible stimulation interval. If no blocking capacitors can be used due tolimited space and the degree of miniaturisation, the passive discharge evenimposes severe risks to the surrounding tissue and the electrode.
