Abstract

When transducer arrays (i.e., arrays of electrode elements) are used to apply alternating electric fields to a subject's body, the subject may experience electrosensation, particularly during portions of the waveform where the amplitude of the AC voltage is ramping up. This electrosensation can be ameliorated by synchronizing the step-to-step transitions in amplitude with the AC signal so that when a given step-to-step transition occurs while the AC signal has a given polarity, the very next step-to-step transitions will occur while the AC signal has the opposite polarity.
