Abstract: A time-dependent element of the present invention includes a time-dependent phase transition material that undergoes solid-solid phase transition developing with time after production irrespective of the presence of an external stimulus, in which one or more physical properties of the time-dependent element selected from a group consisting of composition, volume, transmittance, reflectance, electric resistance, and magnetic property change with time. A physical property temporal change prediction device includes a physical property temporal change prediction device body having the time-dependent element and is configured to predict a temporal change in one or more physical properties selected from a group consisting of composition, volume, transmittance, reflectance, electric resistance, and magnetic property.

Abstract: A functional element includes functional titanium oxide. The functional titanium oxide includes crystal grains of one or more of β-phase trititanium pentoxide (β-Ti3O5) and λ-phase trititanium pentoxide (λ-Ti3O5). The functional titanium oxide includes the property that at least a portion of crystal grains of one or more of β-phase trititanium pentoxide (β-Ti3O5) and λ-phase trititanium pentoxide (λ-Ti3O5) changes into crystal grains of titanium oxide (TiO2) when the functional titanium oxide is heated to 350° C. or higher.

Abstract: a pressure sensor 1 according to the first aspect of the invention includes: a substrate 50; and a functional element 40 which is laid on the substrate 50 and is composed of functional titanium oxide including crystal grains of at least one of β-phase trititanium pentoxide (β-Ti3O5) and λ-phase trititanium pentoxide (λ-Ti3O5) and having the property that at least a portion of crystal grains of at least one of β-phase trititanium pentoxide (β-Ti3O5) and λ-phase trititanium pentoxide (λ-Ti3O5) change into crystal grains of titanium dioxide (TiO2) when the functional titanium oxide is heated to 350° C. or higher. The substrate 50 includes a substrate thin-film section 51 having a thin film form in which the thickness in the stacking direction of the substrate 50 and the functional element 40 is smaller than that in the other directions.
