A film is presented having super-pyroelectric properties. The film comprises nano-sized grains being in a ferroelectric phase and having at least three different crystallographic variants defining at least two polycrystalline macro-domains. The film is shaped to define at least one film region with the macro-domains of a predetermined shape and different orientations of crystallographic axes with respect to the film's surface, thereby enabling to apply a temperature change to the film to induce movement of the polycrystalline macro-domains boundaries enabling super-pyroelectric properties.
