Abstract: Non-invasive “drawable”, or “paintable”, electrode for electrical stimulation or biological signal sensing comprising a pervious and electrically conductive layer (1), at least one electrically insulating element (2) for maintaining the electrically conductive layer (1) separated from the skin (11), and a conductive material (3) that is deposed using a delivery system (4) on desired areas (5) of the electrically conductive layer (1). The conductive material (3) can penetrate the electrically conductive layer (1) and any other part of the electrode underlying the desired areas (5), thus reaching the skin. The conductive material (3) creates an electrical connection between the desired areas (5) of the electrically conductive layer (1) and the skin. Therefore, the shape of the desired areas (5) electrically connected with the skin, can be customized by the user deposing (or “drawing”) the conductive material (3). Thus, the conductive material (3) enables the fabrication of electrodes with custom-shaped electrically conductive areas in desired positions.

Abstract: The present invention relates to polymeric structures, in the form of flat membrane-like surfaces or micro- nanostruc-tures such as capsules, characterized in that it comprises a substantially two-dimensional layer of covalently-bonded monomers of R-substituted metal or metalloid oxides. Said polymeric structures in most embodiments have a crystal architecture with a hexagonal lattice, but the nature of the covalent bonds present therein impart a bending flexibility that make the polymeric structures behave as a “soft” crystal. Methods of producing such structures, composition comprising thereof and method of using thereof are also included within the present disclosure.
