  • Publication number: 20240003762
    Abstract: A functional film includes a strain resistance film provided on one principal surface of a flexible insulating base. The strain resistance film is a chromium nitride thin-film having a thickness of 150 nm or less. In an X-ray diffraction chart with a CuK? ray as an X-ray source, the strain resistance film has an intensity ratio I2/I1 of 0.001 or more, where the intensity ratio I2/I1 is a ratio of the intensity I2 of the second peak in a range in which 2? is 60° to 65° to the intensity I1 of the first peak in a range in which 2? is 43° to 45°. The strain resistance film is less liable to crack due to bending, and has a high gauge factor. The functional film is suitably used for a strain sensor.

  • Publication number: 20220390290
    Abstract: An electroconductive film (101) comprises a metal thin-film (10) on a first main surface of a flexible substrate (40) that includes a resin film (5). The thickness of the flexible substrate is 1 mm or less. The absolute value [H2?H1] of the difference between the heating dimensional change rate H1 of the electroconductive film and the heating dimensional change rate H2 of a film obtained by removing the metal thin-film from the electroconductive film is preferably 0.10% or less. There is a tendency that undulation of a temperature sensor film after patterning of the metal thin-film is further suppressed as the value of [H2?H1] decreases.
