A biomedical electrode structure is presented. The electrode structure comprises a contact member having a tissue interfacing face for contacting a tissue surface, and an opposite electrical coupling face at least a first electrically conductive surface disposed within said tissue interfacing face, and being configured to electrically couple to a portion of the contacted tissue and at least two electrical connectors mounted in a spaced apart relationship on said electrical coupling face and electrically coupled to different regions of said 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.
