Abstract: A multi-tactile feedback component is suitable for an electronic device and includes a thin film deformation element, a thin film vibration element, and a power module. The thin film deformation element has first and second elastic layers and a gain layer disposed therebetween and forming a channel to accommodate a fluid. The thin film vibration element is connected to the thin film deformation element and has a piezoelectric layer and tactile structures. The tactile structures are disposed at a side surface of the piezoelectric layer. The power module is coupled to the thin film deformation element and the thin film vibration element. When the power module supplies an electrical energy to the thin film deformation element, the first elastic layer is deformed to push the fluid and the second elastic layer. When the power module supplies the electrical energy to the thin film vibration element, the piezoelectric layer vibrates.

Abstract: A compression state measuring method is adapted to measure a compressed state of a compressed object compressed by a compressing object. First, at least one image of a first surface region of the compressed object not covered by the compressing object is captured. A first strain distribution value of the first surface region is obtained according to the at least one image. At least one strain distribution function is obtained according to the first strain distribution value. A second strain distribution value of a second surface region of the compressed object covered by the compressing object is obtained according to the at least one strain distribution function.
