摘要： An object of the present invention is to provide a piezoelectric film in which a high sound pressure can be obtained in a case of, for example, being formed into a piezoelectric speaker, and a laminated piezoelectric element obtained by laminating the piezoelectric films. The object is achieved with a piezoelectric film including a piezoelectric layer which contains piezoelectric particles in a matrix containing a polymer material, electrode layers which are provided on both surfaces of the piezoelectric layer, and protective layers which cover the electrode layers, in which, in a case where “ratio D of elastic recovery amount=(elastic recovery amount of piezoelectric layer/elastic recovery amount of protective layer)” is determined in an elastic recovery amount measured by a nanoindentation measurement, the ratio D of the elastic recovery amount satisfies “0.27≤D≤1.19”.

摘要： A rearview assembly is disclosed. The rearview assembly comprises a reflective element and/or a display element. Further, the rearview assembly comprises an array of piezo-electric sensors. The array of piezo-electric sensors may be operable to sense a first vibration. Further, based, at least in part, on sensing the first vibration, the array of piezo-electric sensors may be operable to output a second vibration. In some embodiments, the second vibration may be operable to substantially dampen the first vibration. In other embodiments, the second vibration may be operable to provide haptic feedback to a user interfacing with a touch screen surface of the rearview assembly.
