Electrode sensor kit, electrode assembly, and topical preparation for establishing electrical contact with skin, use thereof, and method of electro-impedance tomography (eit) imaging using these

A method of using an electrode sensor for performing biosignal measurements, comprising

• applying at least one contact element connectable to an analytical instrument and a preparation to skin of a test person, the preparation comprising a mixture of water and at least one lipid forming an emulsion having a conductivity of less than 1 mS/cm for enhancing electrical contact properties between the at least one contact element and the skin of the test person, the preparation interposed between the skin of the test person and the at least one contact element.

The method of claim 44, further comprising determining an electrical value of the biosignal measurements selected from the group consisting of electro impedance tomography measurements, heart-rate-measurements, or electro cardiograph measurements.

An electrode sensor assembly for establishing electrical contact with skin, comprising:

• at least one contact element connectable to an analytical instrument, the at least one contact element comprising a surface for contacting the skin, said surface being coated or impregnated with a preparation comprising a mixture of water and at least one lipid for enhancing electrical contact properties between the contact element and the skin, and said mixture forming a water-in-oil or an oil-in-water emulsion having a conductivity of less than 1 mS/cm.
