| Zusammenfassung: | This invention relates to improved pyroelectric film sensors.
A method for constructing a thin-film infrared photodetector includes providing a thin film including ferroelectric polymer, and applying at least one electrically conductive coating to the polymer so that the coating is nonuniform in surface conductivity to thereby provide an area of higher surface resistance connected to an output region by an area of lower surface resistance. |
