Abstract
The present disclosure provides electrodes that possess hydrogels for contacting skin. In embodiments, an electrode of the present disclosure may include a substrate and a conductive composition on at least a portion of a surface of the substrate, the conductive composition including at least one hydrogel and at least one component capable of providing either a cooling or warming sensation upon electrical stimulation. Methods for forming these hydrogels and electrodes are also provided.
