An electrical multichannel system, particularly for neural stimulation

摘要

The invention relates to an electrical multichannel system (100) and to a neural stimulation and/or recording device comprising such a system. The multichannel system comprises a plurality of application components (130), e.g. stimulation electrodes, and associated access points (120) that are connected by a plurality of electrical lines (110). The resistances of these lines are adjusted to given target values, for example to equal values, by incorporating appropriate tuning sections (140) into the electrical lines. The lines may for example comprise different geometries and/or materials in the tuning sections.

1. An electrical multichannel system, comprising:
a) a plurality of application components and associated access points; b) a multichannel track with a plurality of electrical lines, each line connecting one application component to one access point with a given target resistance and comprising a tuning-section with the following features:
the tuning-section extends between a starting-point and an end-point;the distance between starting-point and end-point is the same for all lines;the resistivity and the cross-section are substantially the same for all lines at their starting-point;the resistivity and the cross-section are substantially the same for all lines at their end-point;the resistances between starting-point and end-point differ between at least one first line and one second line.
