Abstract:
1. A simulated eye, comprising: an eyeball comprising a transparent portion; a circular elastic film comprising a circular portion, wherein the circular portion is visible at the transparent portion and is for simulating a pupil; an inductive coil coiling around the circular elastic film and capable of contracting when being supplied with electric power; a plurality of protrusions protruding inwardly from the eyeball and arranged symmetrically in a circle; and a plurality of elastic elements, each elastic element corresponding to a protrusion, wherein the circular elastic film is surrounded by the circle formed by the plurality of protrusions and elastically coupled to the eyeball via the inductive coil that is connected to the plurality of protrusions through the plurality of elastic elements, and a distance between two opposite protrusions aligned in a diameter of the circular elastic film is longer than a sum of two lengths of an elastic element and the diameter of the circular elastic film when the elastic element and the circular elastic film are not elastically deformed; wherein when the inductive coil is powered down, the circular elastic film is stretched by the plurality of elastic elements, and a size of the circular portion is in a dilated state; and when the inductive coil is supplied with electric power, a radial force pointing toward a center of the circular portion generated by the inductive coil pulls the plurality of elastic elements, and the size of the circular portion is contracted.
