Abstract
Methods and devices for forming painted circuits using multiple layers of electrically conductive paint. In one aspect, a painted circuit includes a substrate (111) and one or more paint layer (106, 108, 110, 112, 114, 116, 120, 122) applied to the substrate, where the one or more paint layers each form an electrical component of the painted circuit. A given paint layer of the one or more paint layers includes a conductive paint formulation having a resistance that is defined by a concentration of conductive material that is included in the conductive paint formulation and a thickness of the given paint layer, and lower concentrations of the conductive material included in the conductive paint formulation provide a higher resistance than higher concentrations of conductive material.
