Abstract
An article is manufactured from a substrate of a material that exhibits the pyroelectric effect by depositing a film containing a selected material in a first state over a front surface of the substrate. At least one electrode is formed on the film, portions of the film being exposed around the electrode. The exposed portions of the film are subjected to a treatment such that they are converted from the first state to a second state, in which the material has a resistivity that lies within a desired range of values.
