ABSTRACT:
A pyroelectric or ferroelectric sensing element consists of a substrate with a thin layer of sodium nitrite. Electrodes may be applied to both sides of the sodium nitrite layer, or, alternatively, only one electrode may be used. In one embodiment, an array of electrodes is applied to one side of a continuous sodium nitrite layer, while the other side has a continuous electrode. In another embodiment, the sodium nitrite layer consists of separate portions, each interposed between one electrode of an electrode array and either the substrate or a second, continuous electrode.
