Biomedical Electrode Assembly With Self-Testing Conductive Surfaces

The electrode's electrically conductive surface is divided into multiple discrete conductive elements (first conductive surface, second conductive surface, third conductive surface) arranged in a specific pattern. This segmentation allows different portions of the electrode to apply electrical signals at different times or with different intensities, creating a more homogeneous overall current distribution across the tissue and reducing patient discomfort.

The electrode is designed to apply electrical signals in a periodic or sequential manner across its different conductive surfaces. By alternating activation between the first, second, and third conductive surfaces, the electrode achieves homogeneous current distribution over time while preventing concentration of current in any single location, thereby reducing patient discomfort.

The electrode incorporates a testing capability that allows the conductive surfaces to be tested before actual clinical use. This preliminary testing verifies that all conductive surfaces (first, second, and third) are functioning properly and establishing appropriate electrical contact with the tissue, ensuring reliable performance before the electrode is activated for signal application or sensing.

The electrode includes built-in testing functionality that provides feedback on the condition and performance of its conductive surfaces. By monitoring the electrical properties of each conductive surface and comparing them against expected parameters, the system can detect degradation due to dehydration or environmental factors and alert users before performance becomes unacceptable.

The electrode integrates multiple conductive surfaces (first, second, and third conductive surfaces) onto a single substrate or backing material, combining what could have been separate components into one unified structure. This merging approach achieves homogeneous current distribution through the multiple surfaces while avoiding the complexity of assembling and managing multiple separate electrode components.

The electrode design makes the conductive surfaces serve multiple functions: they can be individually activated for signal application, used for sensing tissue responses, and tested for performance verification. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing complexity while achieving homogeneous current distribution.
