When treating a subject using alternating electric fields (e.g., using TTFields to treat a tumor), some subjects experience an electrosensation effect when the alternating electric field switches direction. This application describes a variety of approaches for reducing or eliminating this electrosensation. More specifically, during the course of treatment using alternating electric fields, additional electrical signals that reduce the subject's sensation are applied during each of a plurality of time intervals, and these additional electrical signals interact with the relevant nerve cells to reduce the sensations.

A system and method for delivering TTFields are herein described. The system comprises an electric field generator generating a signal having a frequency from 50 kHz to 1 MHz and coupled to a lead. A pad is coupled to the lead and includes a solid continuous phase material and a conductive gel. The solid continuous phase material receives the signal from the lead, has a skin-facing surface, and is constructed of a conductive material or has a conductive material attached to, absorbed into, or adsorbed onto the solid continuous phase material. Pockets intersect the skin-facing surface, the pockets sized and dimensioned to receive a hair shaft. The conductive gel is attached to, absorbed into, or adsorbed onto the skin-facing surface and positioned within some of the pockets.
