摘要：
The present disclosure provides electrodes that possess components capable of indicating to an end-user when the electrode is in need of replacement. The electrode includes a substrate and a conductive composition on at least a portion of a surface of the substrate. In embodiments, the conductive composition includes at least one hydrogel and at least one component that precipitates from the hydrogel after repeated use of the electrode, thereby providing an indication to replace the electrode. In other embodiments, the electrodes include a hydrogel in combination with a pH indicator which changes its color or opacity upon repeated use of the electrode, thereby indicating an appropriate time for changing or replacing the electrode.
