Abstract
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. 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.
Claims6
A medical electrode comprising:
- a substrate;
- and
- a conductive composition on at least a portion of a surface of the substrate, the conductive composition comprising at least one hydrogel and at least one thermochromic material which will change its color or opacity on exposure to heat, thereby providing an indication to replace the electrode.
Dependencies are inferred from the claim text.
