is disposed in conductive communicative contact and connected with the conductive sensor to substantially remove movement of the sensor relative to the conductive adhesive portion, and
is configured to be securely conductively connected to the skin by being adhered to the skin of the subject to substantially remove movement of the conductive sensor relative to the skin to one or both reduce noise or provide a clean signal and to maintain the sensor substantially fixed relative to the skin and thereby one or both reduces or eliminates possible sensor movement relative to the skin for conductive signal communication therethrough from the subject to the conductive sensor;
the at least one additional layer of insulative adhesive being disposed on the continuous sheet of insulative adhesive and covering a part of the sheet of insulative adhesive adjacent the at least one conductive hydrogel portion and covering some but not all of the at least one conductive hydrogel adhesive portion.
