Abstract[English]
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. This electrosensation can be ameliorated by changing the way the voltage ramps up from zero to its peak when the AC voltage is first applied to any given transducer array, and also when the alternating electric field switches direction.[French]
Lorsque des réseaux de transducteurs (c'est-à-dire des réseaux d'éléments d'électrode) sont utilisés pour appliquer des champs électriques alternatifs au corps d'un sujet, le sujet peut subir une électrosensation. La présente électrosensation peut être améliorée en changeant la manière dont la tension augmente de zéro à son pic lorsque la tension alternative est d'abord appliquée à n'importe quel réseau de transducteurs donné, et également lorsque le champ électrique alternatif commute la direction.
