Beschreibung
Zusammenfassung:	The invention utilizes the changes in physical properties of materials during a solid-solid phase transition in order to enhance the sensitivity of cantilever IR detectors. The substantial changes in properties during insulator-to-metal transitions (IMTs) of some materials are useful for controlling purposes according to the invention. A cantilever arrangement is provided with a cantilever being coated with an insulator-to-metal transitions (IMTs) material. Bending of the cantilever is achieved when the temperature of the (IMTs) material is within its phase transition temperature range. A Focal Plane Array (FPA) for detecting Infrared (IR) radiation including the cantilever arrangement of the invention is also proposed.
