Disclosed herein are a system and method for producing paint templates for painting a design on a target surface. The system includes a processor configured to generate a geo-file of paint template designs. The processor includes a design module configured to parse the design into a set of paint sub-designs and a template design module configured to generate the geo-file of paint template designs based on the set of paint sub-designs. The generated geo-file of paint template designs includes a paint template design that corresponds to a paint sub-design. The system further includes a plotter configured to produce a set of paint templates based on the geo-file of paint template designs. Each paint template design includes a set of alignment marks and each paint template is produced with a set of alignment apertures corresponding to the set of alignment marks.

Analyte sensors and methods for fabricating analyte sensors in a roll-to-roll process are provided. In an exemplary embodiment, a method includes providing a roll of a polyester substrate having a first side coated with a layer of platinum, wherein the platinum is in direct contact with the polyester substrate; patterning the layer of platinum to form electrodes; punching the polyester substrate to form ribbons, wherein each ribbon is connected to a remaining polyester substrate web by a tab, and wherein each sensor includes an electrode; after punching the polyester substrate to form ribbons, depositing an enzyme layer over the portions of the working electrodes and coating the working electrodes with a glucose limiting membrane; after depositing the enzyme layer over the portions of the working electrodes and coating the working electrodes with a glucose limiting membrane, singulating the individual sensors by completely separating each individual sensor from the polyester substrate.

An apparatus is disclosed for transferring a pattern of a composition containing particles of an electrically conductive material and a thermally activated adhesive from a surface of a flexible web to a surface of a substrate. The apparatus comprises: respective drive mechanisms for advancing the web and the substrate to a nip through which the web and the substrate pass at the same time and where a pressure roller acts to press the surfaces of the web and the substrate against one another, a heating station for heating at least one of the web and the substrate prior to, or during, passage through the nip, to a temperature at which the adhesive in the composition is activated, a cooling station for cooling the web after passage through the nip, and a separating device for peeling the web away from the substrate after passage through the cooling station, to leave the pattern of composition adhered to the surface of the substrate.

A molecular ink contains a silver carboxylate (e.g. silver neodecanoate), a solvent (e.g. terpineol) and a polymeric binder comprising a polyester, polyimide, polyether imide or any mixture thereof having functional groups that render the polymeric binder compatible with the solvent. Such an ink may have good thermal stability with higher silver carboxylate content.

A method is disclosed for applying an electrical conductor to a solar cell, which comprises providing a flexible membrane with a pattern of groove formed on a first surface thereof, and loading the grooves with a composition comprising conductive particles. The composition is, or may be made, electrically conductive. Once the membrane is loaded, the grooved first surface of the membrane is brought into contact with a front or/and back of a solar cell. A pressure is then applied between the solar cell and the membrane(s) so that the composition loaded to the grooves adheres to the solar cell. The membrane(s) and the solar cell are separated and the composition in the groove is left on the solar cell surface. The electrically conductive particles in the composition are then sintered or otherwise fused to form a pattern of electrical conductor on the solar cell, the pattern corresponding to the pattern formed in the membrane(s).
