Biomedical electrode assembly
First Claim
1. A biomedical electrode structure comprising:
- a contact member having a tissue interfacing face for contacting a tissue surface, and an opposite electrical coupling face;
at least first and second electrically conductive surfaces configured to electrically couple to different first and second portions of the contacted tissue, the first electrically conductive surface being disposed within said tissue interfacing face and the second electrically conductive surface being disposed on the tissue interfacing face and being spaced apart from the first electrically conductive surface;
at least three electrical connectors comprising at least two electrical connectors mounted in a spaced apart relationship on said electrical coupling face and electrically coupled to different regions of said first electrically conductive surface for allowing measurement of at least one electrical property of at least a portion of said at least first electrically conductive surface residing therebetween; and
at least one additional electric connector electrically coupled to said second electrically conductive surface and being configured and operable to sense electric signals propagating in the contacted tissue in response to electric signals applied by the at least first electrically conductive surface.
