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
An electrode sensor kit for establishing electrical contact with skin (2) comprises at least one contact element (3) and a preparation (4) comprising a mixture of water and at least one lipid for enhancing electrical contact properties between said contact element (3) and the skin (2), wherein said mixture forms an emulsion, in particular a water-in-oil or an oil-in- water emulsion, having a conductivity of less than 3 mS/ cm (milli-siemens per centimetre), preferably less than 2 mS/cm and most preferably less than 1 mS/ cm. An electrode assembly (1) for electrical impedance tomography which comprises said kit is characterized in that (a) said at least one contact element (3) forms an electrode or sensor plate, and (b) said at least one contact element (3) comprises a layer of said preparation (4). In an electro impedance tomography (EIT) imaging method above electrode sensor kit or electrode assembly is used for performing bio-signal measurements wherein said preparation (4) and said at least one contact element (3) are applied to the skin (2) of a test person, so that the preparation (4) is interposed between skin (2) and the at least one contact element (3). A topical preparation for enhancing and stabilizing electrical contact properties of the skin comprises a mixture of water and at least a lipid, wherein said mixture forms an oil-in-water or water-in-oil emulsion. A method of determination of at least one electrical voltage or current value or an electrical voltage or current distribution on skin is characterized in that a preparation comprising an oil-in-water or water-in-oil emulsion formed from a mixture of water and at least a lipid is applied to the skin at predetermined locations prior to application of electrical current or voltage and/ or measurement of electrical values at said predetermined locations.La présente invention concerne un kit de capteur destiné à établir un contact électrique avec la peau (2) comprenant au moins un élément de contact (3)
