Concept of local resolution in the design of lead-off electrode systems

  • R. van Steenwijk


A new leading-off electrode system, a concentric bipolar electrode, with higher local resolution than other bipolar electrode systems has been developed. To achieve local resolution improvement, criteria for electrode design were demanded. A theoretical study, near-pass filtering, on the decline of the signal amplitude for increasing observation distances in relation to the size of leading-off surfaces of various unipolar and bipolar electrode systems was performed, and recommendations made for real systems.
