Abstract
When treating a subject using alternating electric fields (e.g., using TTFields to treat a tumor), some subjects experience an electrosensation effect. This electrosensation can be reduced or eliminated by applying a plurality of electrical pulses between two sets of electrode elements positioned on opposite sides of the target region. During the pulses, one set of electrode elements operate as the anode and the other set of electrode elements operate as the cathode. Electrosensation is reduced or eliminated because the collective area of the cathode is at least twice as large as the anode. An electrical signal with the opposite polarity is also applied to charge-balance the plurality of electrical pulses. The plurality of electrical pulses has an average amplitude that is at least twice the average amplitude of the charge-balancing signal.
