Abstract[English]
When transducer arrays (i.e., arrays of electrode elements) are used to apply alternating electric fields (e.g., tumor treating fields or TTFields) to a subject's body, the subject may experience electrosensation. This electrosensation can be ameliorated by changing the way the voltage increases from zero to its peak when the AC voltage is initially applied to the transducer arrays.[French]
Lorsque des réseaux de transducteurs (c'est-à-dire des réseaux d'éléments d'électrode) sont utilisés pour appliquer des champs électriques alternatifs (par exemple, des champs de traitement de tumeur, appelés champs TTF (pour « tumor treating field »)) au corps d'un patient, le patient peut éprouver une électrosensation. Cette électrosensation peut être améliorée en changeant la manière dont la tension augmente de zéro à son pic lorsque la tension alternative est initialement appliquée aux réseaux de transducteurs.
