High impedance signal detection systems and methods for use in electrocardiogram detection systems

A biomedical sensor system comprising a first conductive electrode and a second conductive electrode that is adjacent the first conductive electrode, said first and second conductive electrodes being provided in contact with an anisotropic signal receptive material that is contiguous with both the first conductive electrode and the second conductive electrode and wherein the contiguous receptive material provides that a biomedical signal from a first side of the signal receptive material is detectable by the first conductive electrode that opposes the biomedical signal but is not detectable by the second conductive electrode that does not oppose the biomedical signal irrespective of the thickness of the signal receptive material.

A biomedical sensor system comprising a flexible structural support layer having a first length, a first width, and a first thickness, an electrically conductive layer having a second length, a second width, and a second thickness, and a dielectric material layer having a third length, a third width, and a third thickness, said dielectric material layer including a dielectric material that changes its dielectric properties responsive to the presence of a time varying signal, wherein at least one of the second length and the second width is less than a respective one of the third length and the third width, wherein the dielectric material is contiguous, and provides that a first biomedical signal from a first side of the contiguous dielectric material that opposes the electrically conductive layer is detectable by the electrically conductive layer while another biomedical signal from the first side of the contiguous dielectric material that does not oppose the electrically conductive layer is not detectable by the electrically conductive layer and wherein the third thickness is between about 5 microns and about 200 microns.
