A flexible device, comprising a function component, a first movable member, and a second movable member movably connected to the first movable member. A movement of the second movable member relative to the first movable member causes deformation of the flexible device. By employing the first movable member and second movable member movable relative to each other, deformation of the flexible device of the present invention can be caused by a relative movement between the first movable member and the second movable member, such that the flexible device provides adaptability for application requirements of various scenarios.
