Claim Text:
1. An adherent device to adhere to a skin of a subject, comprising: a stretchable base layer having an upper side and a lower side and an adhesive coating on the lower side to adhere the base layer to the skin of the subject, the base layer having at least two openings extending therethrough, each of the at least two openings having a size; a stretchable covering layer positioned above and adhered to the base layer with an adhesive to define at least two pockets, wherein the stretchable covering layer is thin, flexible, and configured to stretch with the skin of the subject; at least two gels, wherein each gel is positioned within one of the corresponding pockets, each gel having a size larger than the size of the at least two openings to retain said gel substantially within said corresponding pocket; a flexible circuit that includes at least two electrodes in contact with the at least two gels, the flexible circuit including a first portion located on the upper side of the stretchable base layer and a second portion that extends away from the first portion and through an opening in the stretchable covering layer; a circuit carrier positioned above the stretchable covering layer and supported with the stretchable base layer to measure at least one physiologic signal of the subject, wherein the circuit carrier is connected to the at least two electrodes via the second portion extending through an opening in the stretchable covering layer; and a compliant connection that includes a plurality of bridging loops formed between the upper side of the stretchable base layer and the circuit carrier that permits at least some movement of the circuit carrier in a plane parallel to the stretchable base layer.
