Abstract
An electrode assembly for acquiring physiological signals, comprising a flexible substrate having a bottom surface and a top surface, means forming a plurality of electrodes at the bottom surface of the substrate and each electrode having a bottom surface facing away from the substrate, an electrical connector fixed to the substrate and having a plurality of connector elements, a plurality of flexible conductors fixed on the substrate and connecting the electrodes to the connector elements, a layer of conductive adhesive on the bottom surface of each electrode; and an adhesive layer on at least a portion of the bottom surface of the substrate.
Claims7
An electrode assembly for receiving physiological signals, comprising:
- a flexible substrate comprising a first section disposable over the heart and at least three elongated sections extending from the first section having a bottom surface and a top surface;
- means forming a plurality of electrodes at the bottom surface of the substrate at the first section and the elongated sections and each electrode having a bottom surface facing away from the substrate;
- an electrode connector fixed to the substrate and having a plurality of connector elements;
- a plurality of flexible conductors fixed on the substrate and connecting the plurality of electrodes to the connector elements;
- means for adjusting the length of at least one of the three elongated sections of the substrate and the conductors fixed thereto comprising means for releasably retaining the at least one elongated section folded on itself;
- a layer of conductive adhesive on the bottom surface of each electrode;
- and
- an adhesive layer on at least a portion of the bottom surface of the substrate.
An electrode assembly for receiving physiological signals, comprising:
- a first electrode having a single face;
- a plurality of second electrodes, each comprising two side-by-side spaced apart electrode faces;
- and circuit means receptive of signals from each second electrode for subtracting signals at the two side-by-side faces to obtain a difference signal representing only noise.
