In various embodiments the electrically and/or thermally conductive elements (traces, pads, connection elements, electrodes, etc.) may include at least one material selected from the group consisting of: conductive ink, conductive nanoparticle ink, copper, steel, iron, tin, aluminium, silver, gold, platinum, conductive adhesive, carbon fibre, graphene, alloy, silver alloy, zinc, brass, titanium, solder, and any component thereof. The used conductive materials may be optically opaque, translucent and/or transparent at desired wavelengths, such as at least portion of visible light, so as to mask or let the radiation such as visible light to be reflected therefrom, absorbed therein or let through, for instance. As practical examples of feasible conductive material, e.g. Dupont? ME602 or ME603 conductive ink may be utilized.
