A bio-electrode composition contains (A) an ionic polymer material, (B) an addition reaction-curable silicone having at least a hydrosilyl group, (C) a platinum-group catalyst, and a solvent. The bio-electrode composition has a water content of 0.2 mass % or less. The solvent includes one or more of an ether solvent, an ester solvent, and a ketone solvent each of which does not contain a hydroxy group, a carboxyl group, a nitrogen atom, or a thiol group. Thus, present invention provides: a bio-electrode composition capable of forming a living body contact layer for a bio-electrode which is excellent in electric conductivity and biocompatibility, light-weight, and manufacturable at low cost, and which does not leave residue on skin after attachment to and peeling from the skin; a bio-electrode including a living body contact layer formed of the bio-electrode composition; and a method for manufacturing the bio-electrode.

Apparatuses, systems, and methods are disclosed for noninvasive medical diagnostics using electrical impedance metrics and clinical predictors. A method includes applying an electrical current to at least one interrogation electrode placed on a surface of a person's body within a Sappey Plexus region of the person's breast. A method includes measuring an electrical impedance of the person's tissue between the at least one interrogation electrode placed within the Sappey Plexus region of the person's breast and a reference electrode. A method includes comparing the measured electrical impedance to previously-captured electrical impedance measurements of corresponding tissue to determine an indication of a presence of a malignant tumor in the person's tissue.

An electrode sensor involves a solid conductive polymeric substrate shaped as an electrode sensor or portion of an electrode sensor having a layer of silver-coated particles distributed on and embedded into a surface of the substrate. The electrode sensor is particularly useful for ECG electrodes and utilizes less silver without unduly sacrificing performance. A process for producing the electrode sensor involves distributing a layer of silver-coated particles on a surface of a solid conductive polymeric substrate shaped as an electrode sensor or portion of an electrode sensor and thermally embedding the silver-coated particles into the surface. The process is simpler and less costly than existing processes for producing electrode sensors.

A hydrogel pad is configured for use with an electrode or a wearable device to measure vital signs of a patient. The hydrogel pad includes a flexible support having one or more openings in which hydrogel is disposed. A membrane covers one side of the hydrogel to protect it from gaining or losing too much moisture. A removable backing covers the other side of the hydrogel until it is applied to a patient, at which point the other side contacts the patient's skin. The protective membrane can be pierced by an angular conductive contact of a device to contact the hydrogel creating an electric conduit between the patient and the device. When the device is removed, the membrane at least partially closes to cover and protect the hydrogel.
