Abstract

Super absorbent polymer (SAP) is examined as a viable substitute of carbon for transcutaneous stimulation electrode design. Parameters such as fluid release under pressure, current homogeneity, resistance and drying rate were considered. Results showed that SAP electrodes had reduced fluid release under pressure and lower resistance when compared to the sponge electrode. Overall SAP electrodes had lower current homogeneity and less stable drying behavior when compared to the sponge electrode, although SAP current homogeneity was significantly improved by inserting an SAP electrode in a sponge cloth pocket.
