The sensor electrode for electrical impedance tomography, method of manufacture of a sensor electrode for electrical impedance tomography, and use of the sensor electrode.The sensor electrode comprising a matrix of elements of individual contacts spaced (27, 41), and an interface structure (30,35) to form contact between the contact elements mentioned and the skin, the interface structure mentioned comprising a layer of a material interface. Essentially electrically insulating or poorly electrically conductive (20, 29,37) and the contact surface of the skin (31) on one side and a contact surface of the matrix on the other side of the interface layer, a first electrically conductive pattern of a material at the contact surface of the matrix, a second pattern of an electrically conductive material in a The contact surface of the skin, and electrical paths (21,39) connecting the first pattern with the second pattern while, the first pattern comprises pattern elements, each element of the contact individual (27, 41) covers an area of contact surface large enough to cover the various elements patterns of the first standard mencion ADO when contacting with the contact surface of the matrix of interface structure.And through distinct sections of the first pattern with the contact elements of individual groups of tracks provide additional electrical contact with different cross sections of the second pattern, such that each element of the contact individual (27, 41) defines an electrode effective individual in superf\u00edci And skin contact.Manufacturing method of electrode sensor mentioned, characterised by the steps of: to provide understanding of the interface structure mentioned, creating a first pattern of a material electrically conductor on its contact surface of the matrix, a second pattern of a material he Tricamente driver in its contact surface of the skin.Electrically conducting paths connecting the first pattern with the second pattern, and contact sections of
