Stainless steel skin staples—a useful electrode system for long-term electrophysiological measurements in neurosurgery

Summary

Stainless steel staples commonly used for skin suture were tested for their suitability as electrodes for recording electrophysiological data. Investigations were performedin vivo and as well asin vitro, and showed the typical behaviour of electrodes made from a polarizable met al,i.e., an increase of electrode impedance with low frequencies. In spite of this fact most electrophysiological data can be recorded if the input impedance of the amplifier is in the common range of 100 MOhms. Advantage of these electrodes is their quick and easy application, their resistance to mechanical stress and the possibility of leaving them in place for a long time.
