A layered structure is on a support structure's surface. The layered structure can include a component that responds electrically to thermal signals, such as a thermistor, and can also include a layer part that has a printed patterned artifact such as an uneven boundary or an alignment. The support structure can be a polymer layer such as polyimide, and a thermistor can include vanadium oxide with a printed patterned artifact. An array can include a layered structure with thermal sensor cells, at least one of which includes a printed patterned artifact. A layered structure can be produced by depositing a first layer, printing a mask, removing the exposed part of the first layer, depositing a second layer, and lifting off part of the second layer, leaving part of the second layer next to part of the first layer.
